A pregnant Pennsylvania woman who was reportedly just four days away from giving birth and her two young children were among eight victims killed in a mass shooting at an Erie home Friday.

Angelina Stone, who was eight months pregnant, was killed along with her children and several other relatives, according to local reports. 

CBS Pittsburgh reported that Stone was four days away from giving birth, while a family friend told Erie News Now she was expected to deliver "in a couple of days."

A GoFundMe organized to help with funeral expenses identified Stone's children as Isiah and Amari’anna and her unborn baby as Kyrie.

"This situation is horrific and unimaginable," neighbor Jennifer Macko told CBS Pittsburgh.

Lisa Simmers, a family friend, remembered Stone's children as "beautiful, beautiful children" who "definitely did not deserve what happened to them."

"She had a daughter that was almost two, and her son Isiah, who I believe was like four or five," Simmers told Erie News Now.

Erie Police Chief Rick Lorah said Saturday that eight victims were killed in the Friday evening shooting before the suspected gunman, a 45-year-old man, died from what investigators believe was a self-inflicted gunshot wound.

The suspected gunman was related to seven of the eight victims and was the family's patriarch and a grandfather, according to police and a relative who spoke to The Associated Press. The eighth victim was a family friend, Lorah said.

Police Chief Rick Lorah said mental health may have played a role in the shooting but cautioned that it was too early to determine a motive..

Investigators believe all eight victims and the suspected gunman died before officers arrived.

The GoFundMe organizer said the family was seeking help covering funeral expenses for Stone and her children.

"I'm raising funds for Angelina, Isiah, baby girl Amari’anna, and unborn Kyrie after an unthinkable tragedy," the fundraiser states.

The organizer added, "This is more than our family can carry alone right now, and we truly need the community to rally around us. Any donation, no matter the amount, will help ease the financial burden and help us give Angelina, Isiah, Amari’anna, and Kyrie the farewell they deserve."

The Erie Police Department continues to investigate.

The Erie Police Department could not immediately be reached by Fox News Digital for comment.
