A California father who shot his estranged wife before snatching their 9-year-old son was killed in a car crash in Mexico, authorities said Monday.

Lonnie Ramos, 46, was found dead after some kind of car accident in Juarez, Mexico, Orange County Sheriff's Department spokesman Jim Amormino said. The news came after the boy was found safe but alone in a Mormon Church in Juarez on Sunday.

Ryan Ramos was on his way home Monday, a day after the missing 9-year-old boy was found alone in a Mormon Church in Juarez, Mexico, authorities said.

Early Monday, the boy was in El Paso, Texas, awaiting a private flight to Southern California, Amormino said.

Gynnae Ramos, the boy's mother, was in good condition at Mission Hospital, Vasentine said.

After the shooting, a statewide Amber Alert was issued for two cars that Ramos might have been driving. A motor home was added after someone reported renting it to the fugitive.

Authorities then got a tip the father and son had been spotted crossing the border by foot near Andrade, about 160 miles east of San Diego.

The 39-foot purple-and-gold motor home rented by Lonnie Ramos was found there Saturday.

Ramos apparently tried to buy plane tickets for himself and his son at John Wayne Airport on Wednesday night but was unable to do so because he refused to show any identification or provide his name, Amormino said.

Ramos' wife filed for divorce in 2003, and the two have been locked in a divorce and custody battle, court records indicated.
