A registered sex offender was arrested Monday on suspicion of capturing cellphone video of a girl in a restroom in an East County store, and authorities believe there may be others victimized in a similar way.

The 10-year-old victim told sheriff’s deputies a man followed her into the women’s restroom of a Walmart, went into a stall next to her and recorded her with a cellphone camera while making sexual comments, sheriff’s Lt. Dan Brislin said Tuesday.

The suspect was gone when deputies got to the store on Camino Canada near Los Coches Road off Interstate 8, south of Lakeside, on Wednesday.


The girl later identified the suspect through surveillance video obtained from the Walmart. Detectives from the sheriff’s family protection unit arrested Robert Becker, 21, at his Alpine home on Alpine Boulevard near Willows Road off I-8 on Monday.

Becker was booked into jail on charges of attempted lewd and lascivious acts on a minor, annoying or molesting a child with a prior conviction, and disorderly lewd conduct.

Brislin said Becker may have committed similar crimes in East County, and he urged other potential victims to call the sheriff’s department at (858) 974-2417.
