Principal Eric Dean Lewis, of Montague Elementary School in Santa Clara, Calif., was arrested Friday on drug charges.

Eric Dean Lewis, principal of Montague Elementary School in Santa Clara, Calif., was in custody on Monday, following his Friday arrest, and declined NBC Bay Area's request for a jailhouse interview. His bail was set at $25,000. He did not enter a plea during his brief court hearing and was ordered to return on Friday. He was referred to the public defender's office.

Court documents show the 42-year-old Lewis was charged with possessing and transporting with the intent to sell controlled substances including methamphetamine, the club drug GHB and MDMA, otherwise known as Ecstasy. Lewis also faces a lesser charge of having an opium pipe, the documents show. When police showed up at his home, he had 4.8 grams of meth, 7 Ecstasy pills, about 450 grams of GHB and clear baggies, documents state.

Police reports by the Santa Clara County Specialized Enforcement Team that were obtained by NBC Bay Area on Monday show that Lewis became a target in September, after an anonymous tipster told a Mountain View police officer that the principal was selling meth in San Jose and San Francisco.

Last Tuesday, the Mountain View police officer, using an alias, contacted Lewis through an online dating service the principal allegedly used, which is where the principal wrote: "Let's kick it n (sic) blow someclouds. (sic)."

Blowing clouds, the officer wrote, means to smoke methamphetamine. Lewis then told the officer in the pretext conversation that he'd bring the drugs to a San Jose hotel with "the goods," the report states. But then Lewis changed his mind, the report states, saying he'd rather make the exchange in San Francisco. All the while, the report states, Lewis was texting about meth from his workplace in Santa Clara.

On Thursday, the officer secured a search warrant for Lewis' home and car, and was able to arrest him with a team of officers in San Francisco. When he was put into handcuffs, Lewis appeared confused, though he later acknowledged to police that he was the principal of Montague Elementary, the report states.

The news came as a shock to his school community, where he has taught for seven years. He was put on unpaid administrative leave following the arrest.

Santa Clara Unified School District spokeswoman Tabitha Keppler-Hurley told NBC Bay Area on Sunday night that Lewis has been a well-liked principal, and that the community was "in shock" over the allegations.

A college exchange student in California was killed Wednesday after a sand pit he dug with friends collapsed on top of him.

The 20-year-old man, whose name has not been released, was an exchange student from Seoul, South Korea at Master’s College in Santa Clara, Calif. He died of injuries suffered when a large pit that he and other students had dug caved in around him at about 4:50 p.m. at Oxnard Beach Park in Southern California, officials from the Oxnard Fire Department said in a statement.

“I think the kids were just having fun on the beach,” Oxnard Fire Battalion Chief Darwin Base told NBCLosAngeles.com. “There was a big group of them down there. They were taking pictures of each other and from what I understand the individual was laying back in the pit and taking pictures of his fellow students and that’s when it sloughed and came in on him.”

Firefighters arrived to the scene at about 5 p.m. and began digging through the sand with shovels and buckets. The fire department said it took at least 15 minutes to reach the victim.

Rescue crews performed CPR on the man when he was extricated, and he was taken to Ventura County Medical Center, where he was pronounced dead.

Witnesses said the pit in the sand was about six to eight feet deep. It was not known why it collapsed.

Base said digging holes in the sand can be extremely dangerous because the sand and surrounding soil tend to be very unstable. He said lifeguards will warn people who dig holes, but the stretch of beach where the student was buried did not have a lifeguard nearby.

In the New England Journal of Medicine, a group of doctors reported in 2007 they had assembled 52 documented cases involving people buried by sand when a hole collapsed, in which 60 percent of the incidents were fatal, the Ventura County Star reported.

There are no ordinances against digging on the beach in Oxnard.

The man’s name and hometown in Korea have not been released pending the notification of his relatives.
