A 31-year old man was found dead inside a home after a SWAT standoff ended in Santee Friday evening, the San Diego Sheriff's Department (SDSO) confirmed.
The incident happened at approximately 2 p.m. on the 9900 block of Woodglen Vista Drive near Cuyamaca Street.
Deputies say the man had allegedly threatened his mother that he would kill her which prompted the standoff. The suspect was believed to be in possession of weaponds including an ace and a knife.
They were able to get the suspect's mother safely out of the home. Deputies then attemped to make contact with the man, asking him to surrender.
But they say the suspect used a bow to fire arrows at deputies, forcing them to return fire.
"He did not answer except in the form of firing bolts from a crossbow. One of bolts landed in a door jam next to deputes," said Jan Caldwell, spokeswoman for SDSO.
Deputies then set off multiple flashbangs to detect movement inside the home. They discovered that someone was lying on the second floor of the home.
After entering the home, deputies found the man in an upstairs bathroom. He was pronounced dead at the scene.
During the standoff, residents were warned to stay away from the area and to shelter indoors.
NBC 7 spoke to some residents who said the incident surprised them because it considered to be a safe area.
"You don't hear about crossbows," said Mark Hays. "To be shooting them at people is crazy."
Others expressed concern for the mother of the suspect.
"That's just sad--the poor mom," said Johnnie Martinez. "Hope she doesn't feel guilty for it because she had to do what she had to do."
Right now, it's unknown what the cause of death was.
No other information was immediately available.
