A Pennsylvania man is facing trial for allegedly killing his lover over a disputed pregnancy, a case that has shocked the McKeesport community.
Man Charged in Pregnant Lover’s Death
Isaac Smith, 30, is charged with criminal homicide and criminal homicide of an unborn child in the death of 26-year-old Karli Short, who was reportedly five months pregnant at the time. Smith’s trial began recently, and prosecutors say the killing was motivated by Smith’s fear that the pregnancy could ruin his new relationship.
The Shooting Incident
On the morning of September 13, 2021, Short was at her uncle’s home on Furnace Alley in McKeesport, Pennsylvania. Short and Smith had been romantically involved, though Smith claimed it was only a brief relationship.
Short believed the unborn child was Smith’s and had asked him for money and even texted him about a gender reveal party two days earlier, according to court documents obtained by WTAE.
Short’s uncle reportedly overheard her talking on the phone and asking, “Are you coming to the front or the back?” shortly before she walked outside. Moments later, a gunshot was heard. Prosecutors allege that Smith lured her outside and killed her.
Smith’s Post-Shooting Interview
Hours after the shooting, Smith voluntarily went to the Allegheny County Police Department and gave a three-hour interview. He admitted to having been intimate with Short and said he would have been willing to support the child if it was his. Detectives initially believed him, which the defense has emphasized as part of Smith’s argument.
Prosecution’s Case and Motive
Prosecutors argue that Smith had no proof he was the father at the time and acted to protect his new relationship. Allegheny County Deputy District Attorney Ryan Kiray stated that Smith’s motive was clear: he did not want his new girlfriend or family to discover he had a “double life.” DNA tests later revealed that Smith was not the father of Short’s unborn child.
Trial Details and Victim Remembered
The trial is expected to last about two weeks. Karli Short, according to her obituary, was looking forward to becoming a mother for the first time, with her baby due in February 2022.
This case has drawn attention to domestic disputes, the consequences of deception, and the devastating impact of violent actions on families and communities.
