YUMA - Police continued to search for a suspect and a motive Sunday in the deaths of six people found in a home in this southwestern Arizona city.
Authorities released little new information other than to confirm that the victims included a mother and her four children.
"We're considering all options and all potential motives," Police Chief William Robinson said during a news conference at the police station here.
Officers responding to a call of shots fired in a residential neighborhood late Friday found a man with a gunshot wound in the home's backyard. The man, identified Sunday as Luis Rios, 35, died later at a hospital.
Police surrounded the home and evacuated the immediate neighbors. Once inside, police found the other victims. Police wouldn't say where the victims were in the home.
A cause of death won't be released until autopsies are performed Monday, said Officer Clint Norred, a spokesman for the Yuma Police Department.
Police were looking for a man seen running from the scene shortly after the shots were fired. The man was described as Hispanic, in his late 20s or early 30s with stocky build and buzz-cut hair.
Besides Rios, police identified the other victims as: Adrienne Heredia, 30; Danny Heredia III, 6; and Inez Newman, 9. The names of two other victims, both 13-year-old boys, were being withheld. Robinson said Heredia was the mother of all the children.
He said Rios was Heredia's boyfriend.
The couple had been together for about 10 months, said Theresa Guerraro, a friend of Adrienne Heredia who was at the police station Sunday.
Heredia's friends said she had a very good relationship with Rios.
"She was happy for the first time in her life," said Kisty Guerraro, another friend. "He supported her in everything she did."
Theresa Guerraro said she had no idea who the suspect is.
"I know he doesn't have a heart - to kill kids," she said.
