LANCASTER, PA – A Lancaster County man has been sentenced to life in prison, along with an additional five to ten years, for the murder and sexual assault of his wife earlier this year. The ruling was handed down Wednesday by Judge Jeffrey A. Conrad after Matthew Scott Harrison, 49, pleaded guilty to killing his wife, Jami Harrison, in their home.
The fatal incident took place on February 5, 2024, at the couple’s residence in Manheim, located roughly 75 miles west of Philadelphia. Court records show that Jami Harrison was strangled to death, following a disturbing sequence of violent acts perpetrated by her husband.
Matthew Harrison admitted guilt in court to charges of first-degree murder and strangulation. As a result of his plea agreement, prosecutors dropped charges of second-degree murder and aggravated indecent assault. The life sentence ensures Harrison will not be eligible for parole.
During the sentencing, emotions ran high as Jami Harrison’s daughter delivered a victim impact statement. Directing her words at Harrison, she denounced him as a coward and highlighted the impact of losing their mother, whom she described as the family’s only true parent. The daughter recounted the pain and trauma left in the wake of the crime, including the moment her then 11-year-old sister discovered their mother’s body and alerted emergency services.
Investigators stated the 911 call was placed the afternoon of February 5 from their home on E. Mount Hope Road. The young girl reported longstanding abuse, describing Harrison as “really mean” and detailing his history of hurting her mother.
Assistant District Attorneys Fritz Haverstick and Jennifer Ponessa prosecuted the case, pointing to a torrent of hostile and degrading messages Harrison sent to his wife in the days preceding her death. Court filings revealed more than 120 texts, many of which included threats and troubling language that reflected a deteriorating relationship.
Harrison’s communications did not stop with his wife. He also exchanged texts with his son two days before the murder, referencing thoughts of killing Jami Harrison. In those messages, he asked his son if he would be “cool” with him killing her, and alluded to harboring violent thoughts since a prior unspecified incident.
After the killing, Harrison sent another wave of texts—this time to friends and co-workers—hinting at his actions and state of mind. He wrote to a co-worker that he was in “a world of trouble,” would not be returning, and that “the demon in me broke free.” According to statements made to investigators, Harrison claimed to believe he was “setting [his wife] free” through the act.
After his arrest, Harrison told detectives that he thought killing Jami Harrison was what she wanted, further revealing a distorted view of the relationship and events.
In addition to the prison term, the court ordered Harrison to pay $6,500 in restitution. Judge Conrad, reflecting on the gravity of the crime, called the act cowardly and emphasized the suffering endured by the victim’s family.
The case has left the Manheim community reeling, particularly those close to the Harrison family. The loss of Jami Harrison, a mother and central figure in her children’s lives, continues to be felt by her loved ones as they struggle to come to terms with the tragedy.
