Appellant Kimberly Jenkins was convicted by a jury of felony theft by receiving based upon her possession of three “slides” for a sbde bracelet. She was thereafter sentenced to pay a fine of $4,275.00. Ms. Jenkins now appeals, raising four points for reversal.
Ms. Jenkins’s first argument is that the evidence was insufficient to support her conviction. Next, she contends that, if we find sufficient evidence to support her conviction, the conviction should be reduced to a misdemeanor. Third, Ms. Jenkins asserts that the prosecuting attorney made improper arguments to the jury such that reversal is mandated. Finally, Ms. Jenkins argues that the trial court erred in refusing to grant a mistrial due to improper impeachment of Ms. Jenkins during the trial. We affirm.
When an appellant challenges the sufficiency of the evidence, we review the sufficiency argument prior to a review of any alleged trial errors. Lukach v. State, 310 Ark. 119, 835 S.W.2d 852 (1992). The test for determining the sufficiency of the evidence is whether the verdict is supported by substantial evidence, direct or circumstantial. Thomas v. State, 312 Ark. 158, 847 S.W.2d 695 (1993). Substantial evidence is evidence forceful enough to compel a conclusion one way or the other beyond suspicion or conjecture. Lukach v. State, supra. In determining the sufficiency of the evidence, we review the proof in the fight most favorable to the appellee, considering only the evidence that tends to support the verdict. Brown v. State, 309 Ark. 503, 832 S.W.2d 477 (1992).
At the trial in the instant case, Officer Chip Stokes testified on behalf of the State. Officer Stokes stated that he responded to a call from a jewelry store on December 12, 1995. He was informed by the jewelry store owner that Ms. Jenkins was present and was in possession of stolen jewelry. Upon his arrival, Officer Stokes asked Ms. Jenkins how she came into possession of stolen jewelry, and she told him that a friend had purchased it for her from a pawn shop in Dallas, Texas. Ms. Jenkins was then arrested, and according to Officer Stokes she was very cooperative and did not protest. Officer Stokes testified that Ms. Jenkins possessed *4three “slides” that were stolen and that the slides were valued at $275, $275, and $425.
John David Hawks, part owner of JWC Jewelers, testified next. He stated that, on November 30, 1995, Ms. Jenkins came into his store and was interested in buying some jewelry. She then picked out a bracelet and one slide, and put them on layaway. A few days later, Ms. Jenkins entered the store with two “nice looking slides” and told Mr. Hawks to put those slides on the bracelet instead of the slide that she had originally selected. She explained that she received the two slides from her boyfriend in Texas. Mr. Hawks thought the slides looked familiar, and after checking his inventory he discovered that they had been stolen from the store. A few days later, Ms. Jenkins brought in five more slides and told Mr. Hawks to add them to her bracelet. He told her that he would do so, kept the slides, and called Dayer’s Jewelry and found out that one of these slides had been stolen from that store. When Ms. Jenkins returned to pick up her slide bracelet, both jewelry store owners and the police were waiting for her. According to Mr. Hawks, the two slides that had been stolen from his store retailed for $275 and $270.
Danny Cook, also part owner of JWC Jewelers, testified that he recognized the jewelry on the bracelet as that which had been stolen from the store. He asked Ms. Jenkins whether she had been in Dayer’s, and she replied that she had not. According to Mr. Cook, when they accused Ms. Jenkins of theft she sat down and stated, “What happens now,” and acted as if a “bombshell dropped.”
Tommy Dayer, owner of Dayer’s Jewelry, testified that on or about November 30, 1995, Ms. Jenkins came into his store and wanted to look at some slides. One of these slides was eventually discovered missing, and Mr. Dayer testified that this was one of the slides that Ms. Jenkins had given to Mr. Hawks for attachment to her bracelet. The slide was admitted into evidence, and Mr. Dayer identified it as being the slide that was found to be stolen soon after Ms. Jenkins’s visit to his store. He stated that the slide retailed for $400.
*5Ms. Jenkins testified on her own behalf and did not deny that the three slides at issue had been stolen. However, she denied stealing them or having any knowledge that they had been stolen. Rather, she indicated that the slides were a Christmas gift from a friend in Dallas, Texas. She acknowledged being at both JWC Jewelers and Dayer’s Jewelers, but said she did not take any of the slides. Ms. Jenkins admitted that in October 1994 she pleaded guilty to misdemeanor shoplifting. Subsequent to that time, she acquired a teaching job in Conway and held that job through the date of her trial.
Ms. Jenkins’s first point on appeal is a challenge to the sufficiency of the evidence. Arkansas Code Annotated section 5-36-106(a)(Repl. 1993) defines theft by receiving, and provides:
A person commits the offense of theft by receiving if he receives, retains, or disposes of stolen property of another person, knowing that it was stolen or having good reason to believe it was stolen.
Ms. Jenkins submits that, although she was admittedly in possession of stolen property, there was no substantial evidence that she knew or had good reason to know that the property was stolen. She points out that no one saw her take anything from either store, and also points to her testimony that the jewelry was received from her boyfriend as a Christmas present. Ms. Jenkins asserts that it would be totally illogical to buy a bracelet from a jewelry store and then steal slides from the same store and attempt to have them attach the stolen slides. Under these facts, she asserts her conviction was based on speculation and conjecture.
We find substantial evidence to support Ms. Jenkins’s conviction. There was evidence presented to show that Ms. Jenkins viewed the stolen slides prior to the time that they were discovered missing. When confronted at JWC Jewelers, there was evidence that Ms. Jenkins denied ever being in Dayer’s store, when in fact she had been and later so admitted. The jury was entitled to disbelieve her story that a boyfriend from Dallas gave her the slides as a Christmas gift, particularly since she received the slides in early December. Although Ms. Jenkins denied stealing the slides or having knowledge that they were stolen, the jury was *6not required to believe this testimony, particularly since Ms. Jenkins was the person most interested in the outcome of the trial. See Moore v. State, 315 Ark. App. 131, 864 S.W.2d 863 (1993). From all the circumstances, there was ample evidence from which the jury could reasonably conclude that Ms. Jenkins was in possession of property that she knew to be stolen.
Ms. Jenkins next contends that her conviction should at least be reduced to a misdemeanor. She notes that the information charged her with possession of over $500 worth of stolen property, and that the jury was instructed to convict her of a felony if the stolen goods exceeded $200 in value. In 1995, our legislature increased the minimum threshold for felony theft from $200 to $500. See Ark. Code Ann. § 5-36-103(b)(2)(A) (1995 Supp.) However, the legislature did not change the minimum felony threshold for theft by receiving. Nevertheless, Ms. Jenkins submits that, although not explicitly stated by the 1995 amendments, the felony threshold for theft by receiving was also increased due to the language of Ark. Code Ann. § 5-36-102(a)(2) (Repl. 1993), which provides:
A criminal charge of theft may be supported by evidence that it was committed in any manner that would be theft under this chapter, notwithstanding the specification of a different manner in the indictment or information, subject only to the power of the court to ensure fair trial by granting a continuance or other appropriate relief where the conduct of the defense would be prejudiced by lack of fair notice or by surprise.
Ms. Jenkins argues that the jury should have been instructed that the offense was a misdemeanor if the value was $500 or less, and further submits that there was insufficient evidence to prove that the aggregate value of the three slides exceeded $500.
From the abstract presented, it is evident that there was no objection made to the jury instruction now at issue. It is well settled that an argument for reversal will not be considered in the absence of a timely objection. Pharo v. State, 26 Ark. App. 268, 764 S.W.2d 458 (1989). Ms. Jenkins contends that no objection was necessary because this was a “structural error” going to the *7heart of the offense. However, she gives no authority for this proposition. We will not consider assignments of error which are unsupported by convincing argument or citation to authority. Womack v. State, 36 Ark. App. 133, 819 S.W.2d 306 (1991). As a result of Ms. Jenkins’s failure to object, her second point on appeal has not been preserved for our review.
Ms. Jenkins’s next contention is that the prosecuting attorney engaged in improper argument that warrants reversal. Ms. Jenkins essentially contends that the prosecutor repeatedly indicated to the jury that Ms. Jenkins was not presumed to be innocent because she was unable to give an adequate explanation for being in possession of stolen property. Ms. Jenkins acknowledges that no objection was made during the prosecutor’s argument, but asserts that none was necessary to preserve this point because the comments were so egregious that the trial court committed plain error in refusing to correct the statements or admonish the jury.
We need not address Ms. Jenkins’s argument regarding various comments made during the prosecutor’s closing argument. This court has held that there is no “plain error” rule, but instead has consistently held that the burden of obtaining a ruling is on the movant, and unresolved questions and objections are waived and may not be relied upon on appeal. Aaron v. State, 319 Ark. 320, 891 S.W.2d 364 (1995). Ms. Jenkins cites Wicks v. State, 270 Ark. 781, 606 S.W.2d 366 (1980), for the proposition that it is incumbent upon the trial court to intervene, even without an objection, when a prosecutor makes improper comments to the jury. However, in dicta contained in that opinion, the supreme court merely suggested that the trial court may have a duty to correct such an error through an admonition to the jury or granting of a mistrial. The supreme court noted that such an exception to the contemporary objection rule “is a mere possibility, for it has not yet occurred in any case.” Wicks v. State, 270 Ark. at 786, 606 S.W.2d at 369. We decline to extend this hypothetical exception to the general- rule that an objection is necessary to preserve a point for review, and because no objection was made to the prosecutor’s remarks in the instant case, we fail to reach the merits of Ms. Jenkins’s third contention.
*8Ms. Jenkins’s remaining assertion is that the trial court erred in refusing to grant a mistrial due to improper impeachment. On cross-examination, the prosecutor asked Ms. Jenkins whether she informed the Conway Public School System of her misdemeanor theft conviction when she applied for a job as a teacher. Ms. Jenkins replied that she did not disclose that information because her employer did not ask about it. After an objection by the defense, the prosecution stated that it was trying to attack Ms. Jenkins’ credibility by showing that she misled her employer in order to get a job. Then, the defense moved for a mistrial and the trial court denied the motion. Ms. Jenkins now argues that the trial court’s ruling was erroneous because the elicited testimony prejudiced the jury to the extent that she was denied a fair trial. Ms. Jenkins notes that the prosecution presented no proof that the Conway School District even asked about any misdemeanor convictions prior to hiring her.
We find no error in allowing the State to ask the question in dispute. On direct examination, Ms. Jenkins admitted that she had been convicted of misdemeanor shoplifting prior to gaining employment as a school teacher. The State then asked her on cross-examination whether she informed the school district about the conviction. This question was not objectionable because Ms. Jenkins “opened the door” to the question by discussing it on direct examination. See Larimore v. State, 317 Ark. 111, 877 S.W.2d 570 (1994). While we do not know why Ms. Jenkins testified on direct examination about her earlier misdemeanor, it is conceivable that she wanted to display her candor before the court to bolster her credibility. The State could properly then cross-examine her about this testimony and inquire as to whether her candor extended to also telling her employer about the conviction when she was applying for her teaching job. Moreover, any possible prejudice was diminished by the fact that Ms. Jenkins replied that she did not inform the school district about her misdemeanor conviction because the question was not asked when she applied for employment.
A mistrial is an extreme remedy to be used only when it is determined that something has occurred that will undoubtedly deprive a party of a fair trial. Foreman v. State, 328 Ark. 583, *9945 S.W.2d 926 (1997). A trial court has wide discretion when it comes to a motion for a mistrial. Id. In the instant case, we find that the trial court did not abuse its discretion in refusing to find that the contested fine of questioning by the prosecution was improper or prejudiced Ms. Jenkins to such an extent that the granting of a mistrial was necessary.
Affirmed.
Pittman, Jennings, Neal, and Meads, JJ., agree.
