4 things to know about David Conley, accused of killing 8 inside Texas home

A man in Texas has been arrested after a tense standoff and shootout with police Saturday night. He is the main suspect in the deaths of eight people found inside a house. Here's what we know about the case.

Details of the crime: Police attempted to conduct a welfare check at a home in Harris County. When no one would come to the door, and being informed that a man inside had an outstanding warrant for aggravated assault of a family member, police called in a special response unit. After spotting a dead body inside the house, deputies entered the home, and the suspect allegedly started shooting. The deputies pulled back, and a hostage negotiator was able to get the suspect to surrender.

The suspect: The suspect has been identified as David Conley, 49. He was taken into custody by the Harris County Sheriff’s Office. According to the arrest affidavit, the suspect became angry after discovering the locks had been changed on the house after he had moved out. He entered the home through an unlocked window, where he proceeded to restrain and kill the victims. Conley has been charged with multiple counts of capital murder.

Suspect’s criminal record: According to the Houston Chronicle, the suspect’s criminal history is lengthy and includes incidents of domestic violence. In July, Conley was accused of slamming a woman’s head into a refrigerator. The address of that incident is the same as where the eight bodies were found.

In 2013, Conley was accused of assaulting the same woman who was the victim in the July 2015 case. She received an emergency protective order at that time.

A sampling of Conley's criminal record finds that he was convicted of felony retaliation in 2002 and a drug possession charge in 1994.

The victims: Eight victims were found inside the home, including six children and two adults. Their relationship to Conley has not been established at this time. All eight victims were shot in the head and restrained with handcuffs, according to an arrest affidavit. Neighbors told KPRC that they knew the children, and that they were good kids who didn’t want to spend time at home.
