All of the victims of a Pennsylvania mass shooting have been identified after a grandfather killed his family in a murder-[self-death].

Six adults, two children and an unborn baby were killed on Friday when Matthew Stone Sr, 45, opened fire on his family’s home in Erie before he killed himself, the coroner’s office confirmed.

Stone Sr shot and killed his wife, Michelle Stone, 44, their two sons, Jonathan Stone, 19, and Matthew Stone Jr, 21, and their 24-year-old pregnant daughter, Angelina Stone.

Angelina’s unborn child, Kyrie, who was due to be born on Wednesday, and her two other young kids, five-year-old Isaiah and Amari’anna, who was about to turn two, also died in the gunfire, her heartbroken family said in a GoFundMe.

Amari’anna’s father, Juicesiyah Alexander Ezekiel, who also goes by Julius Windham, told Erie News Now: ‘I wouldn’t even put this on my worst enemy. It’s sickening.’

Matthew Stone Sr, 45, opened fire on his family’s home in Erie before he killed himself, the coroner’s office confirmed.

Michelle’s sister, Lora Roberts, 37, and family friend Twila Tanner, 51, died in the shooting while trying to protect the children, according to their fundraiser pages.

The coroner ruled Stone Sr’s death a [self-death], and the other victims were listed as homicides.

All of the victims but Roberts were pronounced dead at the scene, the Erie Times-News reported.

She was transported to a local hospital where she succumbed to her injuries.

Ezekiel said Sunday at a vigil outside of the home that Stone Sr never seemed distressed or out of the ordinary.

‘I think that was a front for him. Him every day, him smiling and being just – you would think of nothing like that would happen,’ he said.

‘It was my baby, bro, and he just took her. Her name was Amari’anna. She was the most beautiful baby God could have created.’

Officers with the Erie Police Department rushed to the scene after a ShotSpotter alerted them to two gunshots on the street where the deadly rampage happened, the agency said.

Video and audio evidence recovered by investigators included muffled gunshot sounds coming from inside the home just before two ‘distressed’ women arrived and began pounding on the door, Erie Police Chief Rick Lorah said.

The gunman then came out and shot them as they ran toward him, before returning inside.

Responding officers found the two women dead outside. After deploying a drone and robot, they went inside and found the bodies of the five-year-old boy and one-year-old girl on the first floor; two more women and two young men in a stairwell; and the shooter on the second floor.

Lorah declined to discuss motive but suggested mental health could be a factor. He said investigators would talk to relatives and examine the cellphones of the women who were killed outside the home.

‘They knew something was going on at that house,’ Lorah said. ‘We have to figure out what that is.’

Lorah also noted that Stone Sr does have a history of prior interactions with the police department, although the last interaction is believed to have been in 2022.

A GoFundMe for Tanner said: ‘On October 9th in Erie, Pennsylvania, Twila Tanner tragically lost her life while bravely trying to help a friend protect her family from a violent and dangerous individual. In a moment of courage and selflessness, Twila put herself in harm’s way to help others.’

Kellie Eggleston created another donation page in memory of Roberts.

Eggleston’s fiancé, Adam Posland, shared the donation page on Facebook, stating that Roberts ‘gave her life trying to save another.’

Roberts is remembered as a loving mother of five children and as being engaged to her fiancé of 14 years, Jeremy, according to her fundraiser.

Family friends Nicole and Debra Eller said Roberts frequently went to the house to help during Angelina’s pregnancy.

Nicole said that Stone Sr ‘was a good guy, and then he started going downhill with everything.’

‘They were a lovely family. Who would have thought this would ever happen?’ Debra added.

‘Oh my gosh, this is so upsetting. This should have never happened to her or the kids or anybody. His grandchildren, his kids- how can you do that?’

At a news conference on Saturday, Erie Mayor Daria Devlin addressed a portion of her remarks directly to the victims’ families.

‘I am so deeply sorry,’ Devlin said. ‘What happened to you was [scary], and there is nothing that any of us can say today that will make this any easier.

‘Our entire community is with you. We’re grieving with you. And we are here to support you.’
