Appeal from the PCRA Order Entered March 6, 2024 In the Court of Common Pleas of Huntingdon County Criminal Division at No(s): CP-31-CR-0000439-1993

BEFORE: MURRAY, J., KING, J., and STEVENS, P.J.E.* MEMORANDUM BY KING, J.: FILED: JULY 31, 2025 Appellant, Catherine A. Dieckman, appeals from the order entered in the Huntingdon County Court of Common Pleas, which denied her first petition filed under the Post Conviction Relief Act (“PCRA”).1 We affirm.

The relevant facts and procedural history of this case are as follows.

The Commonwealth charged Appellant with first degree murder in connection with the murder of her husband, Carl Dieckman (“Victim”). The matter proceeded to a jury trial which commenced on July 12, 1994.

The Commonwealth played for the jury a recording of a call that

Appellant made to the police on Tuesday, October 19, 1993.2 In the call, Appellant reported that Victim went to Delaware with a friend on Friday evening and had not returned as planned. (See N.T. Trial-Day 1, 7/12/1994, at 78-80). Appellant further reported that she had not heard from Victim since he left. (Id.). State Trooper Joseph Pierotti testified that he was assigned to investigate the missing person report and interviewed Appellant on October 20, 1993. (See N.T. Trial-Day 3, 7/14/1994, at 21-22). Appellant told Trooper Pierotti that on October 15, 1993, she dropped Victim at Centre Health and Fitness Club in State College, Pennsylvania. (Id.) From there, Victim planned to go to a car dealership in Delaware with a friend and stay in Delaware overnight. (Id.) She stated that she was unaware of who Victim planned to travel with and where he intended to stay in Delaware. She further reported that she expected Victim to return on Sunday evening, October 16, 1993. (Id.)

Shortly after the interview with Appellant, Trooper Pierotti learned that a body was discovered in the woods. (Id. at 22). The body was subsequently identified as Victim. (Id.) During the course of the investigation, Trooper Pierotti interviewed Appellant’s friend, Ann Kennedy, who provided additional information about Appellant’s involvement in Victim’s death. (Id. at 24-26). Trooper Pierotti arranged for Ms. Kennedy to wear a recording device to record

a conversation with Appellant. (Id.) Shortly thereafter, the police arrested Appellant. (Id.)

Ann Kennedy testified that she and Appellant have been friends for three years. (See N.T. Trial-Day 1 at 85-87). Ms. Kennedy testified that Appellant and Victim separated for a period of time before Victim’s death. (Id.) During the separation, Appellant started dating a man named Steve Brace and moved to Massachusetts to live with him. (Id.). Subsequently, Appellant returned to Pennsylvania and moved back in with Victim. (Id.) Ms. Kennedy testified that although Appellant moved back in with Victim, Appellant planned to divorce Victim and “get his money.” (Id. at 88). Appellant further told Ms. Kennedy that Mr. Brace was going to visit Appellant for a weekend in October 1993. (Id. at 89). Appellant told Ms. Kennedy that Mr. Brace would stay with Appellant in the house for the weekend while Victim was away. (Id.) Appellant planned to hide all of Victim’s belongings when Mr. Brace came to visit. (Id.) On Sunday, October 16, 1993, Appellant told Ms. Kennedy that Mr. Brace’s visit had gone well, and he returned to Massachusetts that morning. (Id. at 90).

On the Thursday following Mr. Brace’s visit, Appellant visited Ms.

Kennedy at work and admitted to Ms. Kennedy that she killed Victim. (Id. at 90-92). Ms. Kennedy reported Appellant’s admission to the police. (Id.). Ms. Kennedy subsequently agreed to wear a recording device for a planned conversation with Appellant. (Id. at 93-94). On October 22, 1993, Ms.

Kennedy had a conversation with Appellant, which was captured by the recording device. (Id.).

This Commonwealth played the recorded conversation for the jury. (Id.

at 100-122). In the recording, Appellant told Ms. Kennedy that Victim did not go to Delaware on Friday. (Id. at 103). Rather, Appellant and Victim went to the grocery store, drove to the woods, and went for a walk. (Id. at 103- 105). Appellant stated that she had a gun in the glove compartment of the car and then in her purse. (Id. at 105). Appellant told Ms. Kennedy that when Appellant and Victim were in the woods, she pulled out the gun, put it to Victim’s chest, and pulled the trigger. (Id. at 106). When Ms. Kennedy asked if Mr. Brace really came to visit her that weekend, Appellant confirmed that he did. (Id. at 103). Appellant further confirmed that Mr. Brace was not involved in Victim’s murder. (Id.)

Officer William Hurley testified that on April 7, 1994, Appellant, with her counsel present, voluntarily provided a statement to the police at the Huntingdon Police Station. (See N.T. Trial-Day 2, 7/13/1994, at 156-57). A recording of the statement was played for the jury. (Id. at 160-298). In the recording, Appellant explained that before October 15, 1993, Victim discovered a gun in the glove box of her car and confronted her about it. (Id. at 162-63). The next day, when she checked her car, the gun was no longer where she kept it. (Id.) On October 15, 1993, she and Victim traveled to State College to complete some errands. (Id. at 163-66). Thereafter, Victim

suggested that they drive to the woods and look at the stars. (Id.).

While they were in the woods, Victim tried to initiate sex with her, but she declined. (Id. at 168-70). Victim took out the gun that he had taken from Appellant’s glove box and started poking her in the shoulder with it, inquiring whether Mr. Brace gave her the gun. (Id.). Victim started pressing the gun into Appellant’s neck, and then her head, arguing with her about her relationship with Mr. Brace. (Id.). Victim demanded oral sex from Appellant while pressing the gun into her forehead. (Id.) Appellant complied with Victim’s demands, and while Victim was distracted, she grabbed the gun and pressed it into his chest. (Id. at 170-71). Victim tried to take the gun back from Appellant, and during the struggle, the gun discharged, wounding Victim. (Id.). Appellant started to get up to go get help. Suddenly, Mr. Brace arrived, pushed Appellant aside, and shot Victim again. (Id.). When Appellant saw that Victim was dead, she ran to the car. (Id.) When she got in the car, she realized that she had the gun in her hand and dropped it on the floor of the car. (Id. at 171-72). Appellant stated that she does not know how Mr. Brace arrived or found them in the woods. (Id. at 218-21). She speculated that he may have followed them but did not recall seeing his car when she ran out of the woods. (Id.)

Appellant stated that when she arrived home, she could not recall anything that happened. (Id. at 172-73). Appellant’s daughter told her that while she was out, Mr. Brace had called from a nearby store and asked for
