THREE people were found dead with stab wounds in an apparent murder-suicide, cops say.

Pasco County Sheriff Chris Nocco said officials were called to the home on Monday for a welfare check when they made the gruesome discovery.

Neighbors in the Wesley Chapel, Florida area reported seeing water coming from the home’s garage and other doors.

Deputies with the Pasco Sheriff’s Office had to enter through a window due to the flooding in the home, Nocco said.

Once inside, they found the bodies of a 70-year-old man and a 63-year-old woman.

Both had stab wounds, deputies said.

Deputies also found the body of a 32-year-old man in a bathtub behind a locked bathroom door.

It appeared that the man – who deputies said was the son of the other two victims – died of self-inflicted injuries.

The bathtub had been running for a long time, officials said.

Officials also said that the three people were likely dead for several days before they were found.

The victims have not yet been identified.

While Nocco called it an isolated incident, he also said it was a “sad situation.”

“We don’t know what caused the son to kill his parents, and then kill himself — what appears to be — but we do know that it was domestic violence,” Nocco said.

Neighbors told deputies that the son appeared to have mental health issues, according to local Fox affiliate WTVT.

“If there is a mental health crisis in your family, please, find help,” Nocco said on Monday night.

Wesley Chapel is located about 25 miles northeast of Tampa.
