The college-aged relative of a woman killed with three children in Utah on Friday night shared a heartbreaking post on Facebook after learning of a fatal shooting on his family’s block.

As Deseret News reports, a woman and three children were killed on Friday night at a home in Grantsville, Utah. A teen male believed to be a relative of the victims is in custody, and a man present at the home survived the shooting.

A Grantsville police source told CrimeOnline that law enforcement has yet to positively identify the victims, pending autopsies, and was not yet certain of the familial relationship between the victims and the suspect. The autopsies are expected to be completed on Monday. The suspect, who is under the age of 18, was transported to a juvenile detention center on Friday night where he will remain until his first court appearance, which could be as early as Tuesday.

Social media posts and a fundraiser referenced in local news indicate that the victims are members of the Haynie family. The fundraiser named Danny Haynie as a benefactor; he is believed to be the college-aged son of the surviving male adult and, presumably, the adult female who was killed.

As the Deseret News reports, the son is a student at the Utah Valley University and posted on Facebook Friday seeking information after learning about the shooting near his family’s home.

“Anyone in Grantsville know (what) is going on??? I can’t get ahold of my family and they live on the street where the shooting happened,” he reportedly wrote on Facebook.

Neighbors told the Deseret News that there were no previous signs of trouble at the home.

“I pray for the family that it happened to and the people that survived that are going to have a really difficult time with it,”  neighbor Laurie Bahe told the newspaper.. “They were a really, really nice family. It’s just shocking that it happened.”
