Erie coroner Lyell Cook named the adults killed Friday on Perry Street.

Monday's list is an identification. Matthew Stone Sr. is dead, so these accounts leave no defendant to charge. Cook's homicide rulings say who died. They do not say why. Chief Rick Lorah told USA TODAY that mental health is at play and that it is too soon for a motive.

USA TODAY, citing the Erie Times-News, reported Monday, Oct. 12, 2026, that Erie County Coroner Lyell Cook identified the adult victims as Twila Tanner, 51; Angelina Stone, 24, who was eight months pregnant; Jonathan Stone, 19; Matthew Stone Jr., 21; Michelle Stone, 44; and Lora Roberts, 37. Cook identified the suspected shooter as Matthew Stone Sr., 45. USA TODAY reported Cook ruled Stone's death a suicide and the deaths of the others as homicides, and that all but Lora Roberts were pronounced dead at the scene. NBC News reported Cook told the network that Stone, 45, died of a self-inflicted gunshot wound after killing six members of his family and two neighbors. NBC News reported the victims included his wife, Michelle Stone, 44; his pregnant daughter, Angelina K. Stone, 24; and his sons, Matthew Stone Jr., 21, and Jonathan Stone, 19. NBC News reported Twila A. Tanner, 51, and Lora Lee Roberts, 37, were neighbors fatally shot outside, and that the Stones lived at the Perry Street home.

Cook did not name the two children. USA TODAY reported he told the Erie Times-News he is not permitted to release the names of a 5-year-old boy and a girl who was 22 months old, because they are under 18, and that Erie police also did not release those names. USA TODAY reported police said the two children were Angelina Stone's children and that they lived at the home with the Stone family. NBC News reported the girl's father, Juicesiyah Alexander Ezekiel, told WICU, "Her name is Amari'anna," and that she was going to turn 2 next month. He told WICU, "I wouldn't even put this on my worst enemy man," and "It's sickening." That name is his public statement. The coroner did not release it.

Cook told NBC News that Angelina Stone was carrying "an unborn fetus who was supposed to have been born today." USA TODAY reported she was eight months pregnant. Erie News Now reported the pregnancy was also a death, that she had been scheduled to be induced Monday, and that its count was nine victims, including the pregnancy, plus the shooter. Cleveland 19 reported 10 total deaths, including the shooter, listed Michelle Stone as 34, and spelled the daughter Angeline. USA TODAY, NBC News, and WTAE reported Michelle Stone as 44 and the daughter as Angelina Stone, and they described eight people killed and the shooter dead. USA TODAY reported no autopsies were performed on any of the victims or the suspect.

USA TODAY reported Lorah said the suspect shot and killed six people inside the house on the evening of Oct. 9, then met two women, including a family friend, outside after they arrived in a "state of distress." Lorah cited surveillance video, USA TODAY reported, and said the gunman shot the two women, went back inside, and shot himself. Erie News Now reported officers were alerted around 4:53 p.m. after a ShotSpotter alert for two gunshots in the 700 block of Perry Street, and that the home was at 722 Perry St. Erie News Now reported the boy and the girl were found on the first floor, and Angelina Stone, Michelle Stone, Jonathan Stone, and Matthew Stone Jr. on the second floor and stairwell. WTAE reported the two women outside were pounding on the door before 5 p.m., and that Michelle Stone was Lora Roberts's sister as well as Stone's wife. WTAE reported Cook said Stone was the father of Jonathan Stone, Matthew Stone Jr., and Angelina Stone.

USA TODAY reported authorities have not determined a motive, and that police are treating the shooting as a domestic situation because many of the victims are related and lived in the same home. Lorah said officers recovered a handgun legally registered to the suspect, and that the suspected shooter last interacted with police in 2022, USA TODAY reported. He did not provide further information on that contact. "I think mental health is at play here, but I think it is too soon to really go into a motive," Lorah said. He also said, "It was horrific." Those are the chief's assessments on Monday's record. They do not settle a motive. The man police describe as the shooter is dead.
