A SWAT standoff in northeast Houston ended with a father shot to death and his son facing charges in the murder.
Investigators said police were called to a home in the 7000 block of Bayan after someone called 911.
Police said the caller told them a family member inside the home, identified by police as Niles Thiboudeaux, allegedly pulled a knife and was threatening another family member.
Kese Smith with the Houston Police Department said when officers arrived, the house was quiet.
"They couldn't see any movement inside," said Kese. "They notified dispatch. Dispatch called the number back and was told by someone who answered the phone that no one had called, and there was no issue there."
Kese said the officers continued to investigate the home when they noticed a light turn off and a person inside the home.
"They decided to see whether the door was unlocked," said Kese. "As he put his hand on the door, he heard a shot fired."
The officers retreated and established a perimeter around the house and called in the SWAT team, said police.
"They came out, along with the hostage negotiation team, and spent several hours trying to negotiate with the suspect," Kese said.
When negotiations proved futile, investigators said they brought in an armored vehicle to try and break through the front door.
"While that armored vehicle was forcing that door down, shots were fired at the armored vehicle," Kese said.
Police said Thiboudeaux then came out the back door with a shotgun and was shot by officers in the torso. He was taken to the hospital in serious but stable condition.
Thiboudeaux's 83-year-old father, Andrew, was later found dead in a back room, apparently from a knife wound, police said.
Thiboudeaux faces charges of murder and aggravated assault on a public servant.
