LAKE HAVASU CITY, Ariz. (CBS/AP) Five people died in a multiple shooting incident Saturday after an man entered a western Arizona home and opened fire, killing the mother of his two children and her new boyfriend among others, before fleeing with the kids to Southern California where he fatally shot himself, according to police.

Lake Havasu City police responded to an emergency call at the Arizona community residence where the alleged gunman, 26-year-old Brian Diez, shot and killed 23-year-old Deborah Langstaff, Primo Verdone- Langstaff's boyfriend-Russell Nyland, 42, and Ashley Nyland, 20. All victims were apparently celebrating Verdone's 24th birthday, according to Lake Havasu City police Sgt. Joe Harrold.

Brock Kelson, 20, and Deborah Nyland, 44, were also wounded, but Kelson died of his injuries early Sunday and Nyland was in intensive care at a Las Vegas hospital Sunday afternoon. In all, six people died.

"This is the worst shooting in the history of Lake Havasu City," said Lt. Richie Sloma, Lake Havasu City Police Department, according to local newspaper Havasu News.

Ashley Nyland was a friend of Langstaff's, and Russell and Deborah Nyland are Ashley's parents, Harrold said. Kelson was Ashley Nyland's boyfriend, Harrold said.

Diez reportedly fled to Rancho Cucamonga, Calif. after the incident, which is located about 250 miles away from Lake Havasu City. Authorities issued an Amber Alert for the two children early Sunday and traced Diez to his sister's residence in the Southern California city a few hours after the shooting.

Around the same time, San Bernardino County Sheriff's Department deputies got a call about a reported suicide at a Rancho Cucamonga residence where authorities found Diez dead of a self-inflicted gunshot wound around 3:30 a.m.

Diez's two children, 4-year-old Kaia Diez and 13-month-old Cole Diez, were found unharmed at a relative's home where her dropped them off before his death, reports the paper.

According to the Lake Havasu City police, Diez fathered the two children with Langstaff during a long-term relationship, but the couple had since become estranged.

Langstaff took out a restraining order earlier this year that denied Diez from seeing her and the children after Diez was accused of slapping their infant son, according to Harrold.

Diez violated the order Aug. 13 when he confronted Langstaff and talked to her, but he did not make any threats toward Langstaff during the encounter, said Harrold.
