Authorities found the bodies of four people Sunday night in a home northwest of Austin, a sheriff's spokesman said.

Travis County Sheriff's spokesman Roger Wade said the cause of death had not been determined, but was believed to be "homicide times four."

Sheriff's investigators were assisting the Jonestown Police Department in securing the area and had attained a search warrant to enter the house late Sunday, Wade said.

Officers responding to a call to the home found the bodies in the home in a Jonestown subdivision, about 15 miles northwest of Austin.

"Some people called the Jonestown Police Department to see if they could check on the welfare of a family member," Wade said.

The people were pronounced dead at about 9:30 p.m. EDT.

Wade did not have information on the identities, age or gender of the dead. He said it has not been determined when the people died.

Authorities had not announced any suspects in the case.

"They want to look at the evidence before we start announcing suspects," Wade said.

Wade described the area as "a subdivision with large lots, lot of trees, in the hills between Lago Vista and Jonestown. It's got some high-dollar houses up in here. It's all houses in among the cedar trees of northwestern Travis County."
