A gunman fatally shot a woman, injured a man and then led police on a wild chase through the Mojave Desert with two hostages in his trunk on Friday before he was killed in a shootout.
Sergio Munoz, 39, who has a lengthy criminal record dating back at least two decades, began his rampage before dawn when he attacked the couple at the small house where he had been staying.
Later, he called an officer on his cellphone and said he wanted to deliver a package to police and kill officers but, because he would be outgunned, he would "wreak havoc" elsewhere, Kern County Sheriff Donny Youngblood said at a press conference.
Police now believe the "package" was the hostages, Youngblood said.
Nearly two hours later, a sheriff's deputy spotted Munoz's car and a pursuit began over roughly 30 miles of highway, through arid stretches of desert about 150 miles north of Los Angeles. He ran traffic off the road, firing at least 10 times at passing vehicles with a shotgun and a handgun. No motorists were hurt, Youngblood said.
At one point during the chase, which lasted more than 40 minutes, Munoz pulled over and the car's trunk popped open, revealing a man and woman inside, the sheriff said. Munoz then got back in the car and sped off.
At some point, Munoz told pursuing officers, "'I'm going to shoot them,'" Youngblood said.
In the end, Munoz pulled over again on U.S. 395, turned in his seat and began shooting into the trunk. As many as seven officers opened fire and killed him.
The hostages were flown to a hospital and were listed in critical condition, but expected to survive.
Authorities didn't say what triggered the rampage, but there were signs that Munoz's life had been unraveling.
Ridgecrest police said Munoz had lost his job recently.
The sister of the man wounded in the pre-dawn shooting said Munoz was a heroin dealer that had been staying at her brother's house for about two weeks.
Dawn Meier told The Associated Press her brother, Thaddeus Meier, told her Munoz was a good friend he wanted to help out so let him crash, but that Munoz had been using and dealing black tar heroin.
She had moved out of the house a week ago to join her boyfriend, who lived next door, after he insisted she get her 7-month-old son away from the drug-related traffic.
Her boyfriend, Derrick Holland, said that on Thursday he heard Munoz complaining in the yard about how his life was falling apart and he was losing everything "due to drugs."
Early Friday morning, Munoz showed up and told Thaddeus Meier, "We're going to reduce all of the snitches in town," Dawn Meier said her brother recounted from the hospital.
When her brother declined, Munoz shot him at least twice, then shot and killed his girlfriend.
Munoz is a felon with convictions dating back to 1994, when he was sentenced to more than two years in prison for receiving stolen property.
In May, he was arrested for possessing ammunition as a felon, but the felony charge was dismissed. Munoz was most recently arrested Sunday for investigation of possessing controlled substance paraphernalia and a felony charge of possessing ammunition as a felon. Dawn Meier said police found a syringe at the home where the slaying would happen five days later.
There was some information that Munoz was using Facebook during the pursuit, but it wasn't immediately clear what the postings were, Youngblood said. Investigators recovered the shotgun and a handgun.
A crime scene was set up along U.S. 395 at Kramer Junction, where two police helicopters landed amid numerous law enforcement vehicles. The highway was closed from Kramer Junction for 10 miles north because of the investigation.
Schools in Ridgecrest were placed on lockdown as a precaution but were later reopened.
