The shooting appeared to have been isolated and there was no indication a shooter is on the loose, police said.
DENVER — Two children under 10 years old and a woman were killed, and a third child was wounded at a house in northeast Denver, police said Wednesday.
That child was in critical condition at Denver Health Medical Center.
Officers were called to the home about 6:55 a.m. for reports of a shooting, denverpost.com reported. Police said they were seeking a warrant to further search the property.
Lt. Matt Murray, a police spokesman, said no arrests have been made. He said detectives were not searching for a person of interest, but would not elaborate, according to denverpost.com.
"We have no reason at this point to suspect a killer is on the loose," Murray told reporters. "It's isolated to this address."
The neighborhood is in an industrial area, surrounded by warehouses and a trucking terminal, near the National Western Stock Show complex.
Neighbor Debbie Martinez said the house was recently remodeled, and she saw a family of five — 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 considered stricter gun laws and President Barack Obama tried to rally national support for a ban on assault weapons.
