A Southern California man who police say shot his estranged wife and kidnapped their son was killed Sunday after being hit by a bus in Mexico.

Lonnie Ramos, 46, sparked an Amber Alert in Utah last week when police believed he could be in the state with his 9-year-old son, Ryan Ramos. He was found Sunday alone on the grounds of the LDS temple in Juarez and reunited with his family.

After apparently dropping his son off at the church building, Lonnie Ramos died Sunday afternoon when he was hit by a bus while he a crossed a busy street in Juarez, said Orange County sheriff's spokesman Jim Amormino. The man was taken to a nearby hospital where he was pronounced dead.

"They're treating it as an accident," Amormino said. "As protocol, the driver has been arrested by Mexican police."

On Wednesday, police said Lonnie Ramos shot his estranged wife, Gynnae Ramos, in the face with a handgun as she waited in her car to pick up her son. The man then took their son across the border into Mexico.

"He believed he was on an outing with his father," Amormino said. Detectives now believe Lonnie Ramos had planned the shooting.

Gynnae Ramos was in good condition Monday in a California hospital where she was recovering from gunshot wounds to her chest, stomach and eye.

And after a frantic five-day search, Ryan Ramos was safe and by his mother's bedside Monday.

"The boy is doing very well," Amormino said, "but he doesn't know all of the details of what has happened."

On Sunday morning, Lonnie Ramos called his father in Washington, D.C., to say that he was in Juarez with his son, who he had dropped off at the LDS temple. Lonnie Ramos converted to The Church of Jesus Christ of Latter-day Saints about eight months ago, police said.

Ryan Ramos was taken from Juarez to the U.S. consulate in nearby El Paso, Texas, and flown to Orange County. He did not know that his mother had been shot or that his father had died when police found him, Amormino said.
