A Philadelphia-area couple was discovered dead in their home by their teen son on Tuesday, bearing what authorities say were "severe" cuts from a chainsaw, the Associated Press reports.

From NBC Philadelphia:

The 14-year-old boy called police around 12:50 p.m. and reported he found his parents unresponsive with lacerations from a chainsaw in their home on the 1100 block of Country Lane in Lower Moreland. Police arrived at the home and found the bodies of the 48-year-old man and his 43-year-old wife inside.

"The death of the female seems to be an apparent homicide, however, the investigation is continuing," said First Assistant District Attorney Kevin Steele. "This is preliminary at this point."

Steele told The Intelligencer a chainsaw was found inside the house.

According to WPVI-TV, police had been called to the home in the past for unspecified domestic issues. Autopsies to determine cause of death are scheduled for Wednesday.
