The case of Gregory Serrano, 34, of Monrovia, is due to go to trial Tuesday at Pasadena Superior Court, according to court officials.

Serrano is accused of using the Internet to lure, molest and take pornographic pictures of 10 underage girls.

His trial has been postponed several times already, so we’ll see if this time it sticks.

Serrano has been charged with 20 counts of child molestation in the alleged crimes, which Los Angeles County District Attorney’s officials say date back to June of 2006, United States Attorney Joey Blanch said.

In addition to the local charges, Serrano has been indicted on 23 federal charges including using the Internet to entice minors, producing and possessing child pornography and destroying evidence, United States Attorney’s officials said.

Serrano was arrested March 12 after a 15-year-old girl reported the alleged molestation to her parents, officials said.

The alleged victims in the case range in age from 13 to 17, said Blanch.

If convicted on the federal charges alone, Serrano could face a sentence of life in prison, she added.
