A man was shot and killed at a house party in northeast Houston early Sunday morning, police say.

According to the Houston Police Department, the shooting took place around 2:30 a.m. at a home located on Waterside View Court near Catherine Bay.

Police say there was some sort of altercation between four men which started inside the home then went outside. At some point, a gun went off and a man was killed.

"We aren't sure if it was some type of accidental discharge or if somebody actually pulled the trigger," said Shaun Sylvester with HPD.

Police say they all knew each other, and the suspect immediately turned himself in. They haven't determined if the victim was a part of the altercation.

At this time, it isn't know what the argument was over.

The investigation is ongoing.
