DENVER (AP/CBS4) — Police were waiting Thursday for autopsy reports after two children and their mother were found dead in a shooting at a Denver home. Another child was in critical condition.

Police have not released the names of the victims, and the causes of death were under investigation, chief deputy coroner Michelle Weiss-Samaras said.

However, relatives told Denver media outlets the woman was the mother of the children. They said her husband had left their home Tuesday night to cool off after a quarrel.

Liliana Castro told The Denver Post the dead woman was her sister, and her sister’s husband told her that he had come home Wednesday morning to find the bodies.

Police said no arrests have been made, and they weren’t searching for any suspects.

“Is there a mass killer or someone running around? At this time we don’t believe so,” police Major Crimes Cmdr. Ron Saunier said.

The house is located in an industrial area near the National Western Stock Show complex.

Neighbor Debbie Martinez said she saw a family of two adults and three children move in about six months ago.

“They seem like outgoing people. They didn’t bother anybody,” she said.

On a corner about a block from the scene, members of nearby Providence Bible Church gathered in a circle to prayer.

“Basically, we pray for the community,” said Jose Rojas, pastor of the church.

“This is the horror of the whole country. There are all these shootings,” he said. “I think it’s too much, too much to see innocent people being killed.”

The deaths came as the Colorado Legislature considers stricter gun laws and President Barack Obama tries to rally national support for a ban on assault weapons.
