RIVERSIDE - Adan Sanchez, the popular young Mexican balladeer killed in a car wreck last week, was mourned at a private funeral Friday, the morning after a huge crowd turned unruly while waiting outside another church for a viewing of the body.

About 100 people attended Mass at St. Anthony of Padua Roman Catholic Church. Award-winning vocalist Lupillo Rivera sang and two brass orchestras played "Te Vas, Angel Mio" ("You're Leaving, My Angel").

Sanchez, the 19-year-old son of the late narco-ballad singer Marcelino "Chalino" Sanchez, died March 27 in a car crash in the Mexican state of Sinaloa.

Three other people were in the car, including his manager, Lorena Rodriguez of Santa Ana, Calif., according to Univision Music Group, which produced Sanchez's albums.

Sanchez, who lived in Southern California, recorded nine CDs that included romantic ballads and tributes to his father. He had a large listening audience in Mexico and the United States.

The family was able to keep the location of Friday's funeral secret until after it started. It was held in Riverside County, about 35 miles east of the Los Angeles County community of Norwalk, where on Thursday night about 10,000 mourners gathered outside a church to pay their respects.

But when the viewing ended 90 minutes early, disappointed fans ran into the streets, rocking cars and overturning portable toilets. A vehicle carrying Sanchez's body was mobbed by fans and showered with flowers.

No arrests were made and there were a handful of minor injuries.

Family friend Nick Gonzales told KCAL-TV that the decision to move the funeral to an undisclosed location wasn't made until after Thursday's raucous gathering.

Sanchez was adored by fans, who said he liked to meet with them after concerts and spoke of Mexico and his father in his songs.

"He was probably going to be very famous," fan Juana Toma told KCAL. "It was just the beginning."

Fans were first shaken by the death of Sanchez's father in 1992 and now the rising star.

Marcelino Sanchez emerged as one of the mythical figures of the narco-corrido - or drug-ballad - scene. His cocked cowboy hat and pistol-waving bravado inspired fans to imitate his flashy swagger. His songs celebrated the bravery of drug lords and memorialized their often violent ends.

His reputation grew after he survived an on-stage gunfight, before he was abducted and killed in the same state where his son died.
