A San Bernardino County school bus driver was arrested and charged with possessing more than 10,000 images of child pornography, the U.S. Attorney’s Office announced March 28.

The man was identified as Donal James Seaver, 49, of Hesperia, who had been working as a school bus driver for a private company.

He drove a route for 10 elementary school students with special needs, the U.S. Attorney’s Office said in a statement.

Police found a computer tablet that had 10,000 images and 13 videos of child sexual abuse material at the suspect’s residence during a search March 7, authorities said.

Officials said that the tablet’s history data was “wiped” frequently to delete data on the device. The most recent reset was in late February.

A judge ordered Mr. Seaver to be taken into custody, without a bond. An arraignment is scheduled for April 16.

Mr. Seaver could spend a maximum of 20 years in federal prison if convicted.

The FBI and the San Bernardino County Sheriff’s Department are investigating this case, according to the authorities.
