Wayne Silvria Gayle ("Appellant") appeals from the order of the Court of Common Pleas of Northampton County, in which the trial court denied his Petition for Return of Property, to wit, seven screenplays and one novel he claims to have authored while he was previously incarcerated. According to Appellant, police confiscated the papers from his residential safe during execution of a search warrant as part of a narcotics investigation of his home address. Upon careful review of the record, we affirm.1
The trial court presided over the June 30, 2015, evidentiary hearing on Appellant's petition. The Commonwealth presented evidence that on May 2, 2014, the narcotics unit of the Easton Police Department culminated its investigation of Appellant's *190suspected illicit drug trafficking at his mother's residence with the execution of a search warrant. As part of his duties as case officer in charge of the investigation, Officer Brian Burd collected evidence from the search and placed it in a plastic bin he carried throughout the home. N.T. 6/30/15 at 83, 85-86. Burd denied observing anything resembling manuscripts during his search of the home and the safe in question. N.T. at 88, 89. Inspector Salvatore Crisafulli, supervisor of the narcotics unit, observed Burd in this regard and noticed no paper items in the bin other than three pieces of mail. N.T. at 74-76, 81. In response to Appellant's petition, Crisafulli searched the evidence room at the Easton Police Department and found no manuscripts or other writings among the items seized during the search. N.T. at 78-79.
Appellant claimed that his bedroom safe stored seven screenplay manuscripts and one novel manuscript, each approximately 120 pages long, that he had authored in prison and mailed to his brother, Albert, for safekeeping. N.T. at 38, 40.2 Albert testified at the hearing that he had placed the manuscripts in Appellant's safe at various times prior to Appellant's February of 2013 release from prison, pursuant to Appellant's instructions. N.T. at 8-10. He did not view the contents of the safe again until after the May 2, 2015 search, at which time he observed an empty safe. N.T. at 12, 13.
Appellant's other brother, Baltimore, lived at the address but denied ever looking into Appellant's bedroom safe. N.T. at 17. Baltimore was present on the morning of the search, and, according to his testimony, he asked officers where they were going with a plastic bin full of Appellant's papers. N.T. at 20, 22, 27. Appellant's mother, Louise Gayle, was the principal resident of the address and had lived there for over twenty years, but she was not home on the morning of the search. N.T. at 29. She arrived at the home to find several officers standing on her porch holding a plastic bin filled with a "pile of papers," she testified. N.T. at 30. Once inside, she observed that the safe in Appellant's bedroom had been forcibly opened, but she could not say what, if anything, had been removed because she had never before looked inside the safe. N.T. at 31, 35.
By order of August 12, 2015, the trial court denied Appellant's petition as moot given the lack of evidence that the Commonwealth possesses, or ever possessed, the manuscripts in question. On September 11, 2015, Appellant filed a timely notice of appeal. He raises one question for our review:
Even a minimum showing will satisfy a petitioner's initial burden of proof in a motion for return of property.[ ]Did the trial court err in dismissing this petition as moot where the Appellant presented evidence that (a) he stored manuscripts in a safe at 1139 Butler Street (b) the police emptied the safe while executing a search warrant and (c) the police departed with a bin containing numerous documents?
Appellant's brief at 5 (footnote omitted).
We initially recognize that an appellate court's review of a trial court's decision on petition for return of property is limited to examining whether findings of *191fact made by the trial court are supported by competent evidence and whether the trial court abused its discretion or committed error of law. Commonwealth v. Wintel, Inc., 829 A.2d 753 (Pa.Cmwlth.2003).
Regarding the manuscripts, we agree with the Commonwealth that Appellant's claim is moot. See Commonwealth v. Matsinger, 68 A.3d 390 (Pa.Cmwlth.2013) (holding where the Commonwealth is not in possession of property in question, petition for return of property is moot). Here, questions pertaining to whether manuscripts were located in the bedroom safe and whether investigators confiscated the manuscripts were matters of credibility, which the trial court resolved in the Commonwealth's favor. Pivotal to the court's decision was the absence of the manuscripts from the search inventory list of items seized from the residence, Inspector Crisafulli's testimony that his thorough search of the Easton Police Department's property room pursuant to Appellant's petition yielded no manuscripts, and the admissions of Baltimore and Louise Gayle that they neither knew what Appellant stored in his safe prior to the search nor identified paperwork in Officer Burd's bin as the alleged manuscripts in question. We, therefore, conclude that competent evidence supports the lower court's decision, and in this respect we adopt the court's Order of August 12, 2015, which comprises the findings of fact and conclusions of law central to the court's determination.
Order is AFFIRMED.

CONCLUSIONS OF LAW
1. A person aggrieved by a search and seizure may move for the return of property to which he is entitled lawful possession. See Pa.R.Crim.P. 588. Unlike forfeiture actions, proceedings for the return of property arise under the Rules of Criminal Procedure. Specifically, Rule 588 provides:
(A) A person aggrieved by a search and seizure, whether or not executed pursuant to a warrant, may move for the return of the property on the ground that he or she is entitled to lawful possession thereof. Such motion shall be filed in the court of common pleas for the judicial district in which the property was seized.
(B) The judge hearing such motion shall receive evidence on any issue of fact necessary to the decision thereon. If the motion is granted, the property shall be restored unless the court determines that such property is contraband, in which case the court may order the property forfeited.
Pa.R.Crim.P. 588.
2. The claimant must first establish that he is an "aggrieved person" of a search and seizure entitled to the lawful possession of the property. In re One 1988 Toyota Corolla (Blue Two-Door Sedan) Pa. License TPV 291, 675 A.2d 1290, 1295 (Pa.Cmwlth.1996). The burden then shifts to the Commonwealth to establish that the property is contraband or derivative contraband. Id.
3. However, a motion for return of property must be dismissed as moot if the Commonwealth does not possess the property at the time of the hearing. Commonwealth v. Matsinger, 68 A.3d 390, 396 (Pa.Cmwlth.2013) (citing Commonwealth v. One 1978 Lincoln Mark V., 52 Pa.Cmwlth. 353, 415 A.2d 1000 (1980) ).
4. Here, the Commonwealth asserts that it is not in possession of Defendant's screenplays or novel. These items were not identified on the search inventory sheet as having been seized from the residence at 1139 Butler Street. Inspector Crisafulli searched the police department property room and confirmed that the Easton Police do not possess Defendant's writings. Defendant's two witnesses who were present during the search, Baltimore Gayle and Louise Gayle, could not identify the papers in Officer Burd's plastic bin as *194Defendant's manuscripts. They further testified that they did not know what was in Defendant's safe prior to the execution of the search warrant. Officer Burd testified that the only items seized from the residence were three pieces of mail, which were listed on the inventory.
5. Based on the foregoing, we must find that Defendant's Petition for Return of Property is moot, as there is no evidence that the Commonwealth possesses, or ever possessed, the property in question.
