Updated:ARNOLD, Pa. —
Authorities in Westmoreland County continue to investigate what they believe to be a double homicide of a mother and her son.
The bodies were found inside an Arnold home late Thursday night.
A family friend, who became worried after not seeing the victims for a few days, went to their Third Avenue house. The friend called police after spotting one of the victims through a window.
Investigators told Channel 11 News that officers subsequently forced their way into the home, making the tragic discovery at approximately 11:20 p.m.
The victims were later identified as Bonnie Lee Broadwater and her son, Lance Holt.
The deaths are being treated as homicides. Authorities said that the decomposing bodies, found close together, were likely inside the home for at least two days. Arnold Police Chief Willie Weber called the deaths suspicious.
According to authorities, there were visible signs of trauma, but exactly what happened remains a mystery.
"They were nice people," said Paula Brown, who lives next door. "They didn't mess with nobody, and I thought nobody messed with them, but appears somebody did."
Brown said that she knew something was wrong.
"I never smelled death before, and that's what is creeping me out," Brown told Channel 11 News. "I'm shocked."
Neighbors reported hearing the victims' two pit bulls start to whimper earlier in the week.
