COMMONWEALTH OF PENNSYLVANIA : IN THE SUPERIOR COURT OF : PENNSYLVANIA : v. : : : CATHERINE A. DIECKMAN : : Appellant : No. 482 MDA 2024

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

1 42 Pa.C.S.A. §§ 9541-9546. J-A11023-25

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

-2- J-A11023-25

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.

-3- J-A11023-25

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

-4- J-A11023-25

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).
