A woman and two boys were found stabbed to death at a Dallas home and two teenage girls were found bound and gagged in a closet, police said. The suspect remained at large Sunday.

A capital murder warrant was issued Saturday for Robert Sparks, 33, who is believed to be related to the victims, said Lt. Vernon Hale, a police spokesman.

The girls were taken to a hospital and believed to be in good condition, police said. They did not release their names or the nature of their injuries.

"They have been through an extremely traumatic experience," Hale said.

Authorities identified the victims as Chare Agnew, 30; Raeqwon Agnew, 10; and Harold Sublet, 9.

Hale told The Dallas Morning News the woman was believed to be the mother of all four children.

Sparks has previously been arrested in Dallas County on suspicion of aggravated robbery with a deadly weapon, assault and evading arrest, according to county records.
