Two adults and three children were found dead in a Massachusetts home on Monday morning.

According to CBS Boston, police were called to a townhouse in Abington by a relative who went to the home at about 7:30 a.m. Monday to take a child to school. Authorities found the bodies of a 43-year-old man and a 40-year-old woman along with their three children: an 11-year-old girl and 9-year-old twins, a boy and a girl.

Plymouth County District Attorney Tim Cruz told the news station that while all five victims appeared to have been shot, a medical examiner is still working to determine the precise cause of death.

The deaths appear to be the result of a murder-suicide, but it is unclear who killed the others.

“There’s not a lot of answers to a heck of a lot of questions,” Cruz told CBS Boston.
