Suspect found shot to death after slaying

A Mohave County sheriff's office spokeswoman said a suspect in a Monday morning homicide in north Kingman apparently killed himself at the end of a police pursuit east of the city in northwest Arizona.

Spokeswoman Trish Carter said Margaret Cappello, 68, was shot and killed and her husband, Glen Cappello, 71, was wounded at their home in the 9300 block of Avenida Obregon.

The husband was airlifted to University Medical Center in Las Vegas. Carter said he identified his attacker as Stephen Richard Luxton, 54, a man who is believed to have lived with the couple.

"At about 12:30 p.m., deputies received information that the suspect had a handgun in his possession and he was in a convertible Pontiac Trans Am," Carter said. She said Kingman police spotted the suspect's vehicle leaving the city eastbound on Interstate 40.

Carter said the police pursuit ended about 10 miles east of Kingman. After police used "stop sticks" to flatten one of the Trans Am's tires, the vehicle pulled over. When officers converged on the car they found Luxton dead, apparently from a self-inflicted gunshot wound.

Authorities said they were trying to determine what caused the attack at the Capello home.
