DENVER (AP) -- A mother shot and killed two of her young children and critically wounded another before taking her own life in a Denver home, police said Thursday.
The surviving child, Isabel Perez, was hospitalized in critical condition in a deep coma, said Dr. Claudia Kunrath of Denver Health.
Authorities didn't immediately release the names of the other victims.
Relatives have said the woman quarreled Tuesday night with her husband, who left their home to cool off and found the bodies when he returned early Wednesday.
"Me being the brother of the person who caused this tragedy, I wish I can say or express in words a 'sorry.' But what's done is done," the children's uncle Tony Nunez said at a news conference.
Nunez didn't take questions and said his focus is on prayers for his niece. He thanked community members who have offered support.
Police said no arrests have been made, and they weren't searching for any suspects.
The house where the bodies were found is in an industrial area near the National Western Stock Show complex.
