Man, 50, sought for using minor to sell weed at high school

Authorities on Wednesday, Dec. 6, asked the public to help locate a San Diego man charged with using a juvenile to sell marijuana to students at a Carmel Valley-area school, as well as supplying pot to minors.

San Diego police investigators said William John Sipperley may be armed, and may have left the area. He may be hiding in Oregon, Hawaii or possibly in the Las Vegas area.

An arrest warrant was issued for Sipperley in October. He was last seen in September, a police detective said.

Sipperley, 50, is charged in the same case as fiancée Kimberly Quach, a Cathedral Catholic High School parent arrested in October on suspicion of using a teenager to sell drugs at the school.

A search warrant affidavit that San Diego police investigators filed Oct. 3 alleged that Quach showed the teen how to make the sales, and that customers paid in cash or through online payments.

According to that document, a search of the home the couple shared with two minor children turned up marijuana plants drying on tables throughout the home, as well as planters, grow lights and other items used to grow the plants.

In early October, Quach pleaded not guilty to 37 counts, including 10 charges of employing a minor to sell or carry marijuana, and 16 counts of furnishing marijuana to a minor over the age of 14.

The 48-year-old remains jailed in lieu of $201,000. Her preliminary hearing is set for February.

Sipperley is white, 5-feet, 9-inches tall and 180 pounds, with brown hair and brown eyes. Authorities said he might be driving a white 2007 Honda with a California license plate of 7PES884.

Anyone with information about Sipperley’s whereabouts can call Crime Stoppers anonymously at (888) 580-8477. Texts or web tips can also be sent at sdcrimestoppers.com.

Tipsters may be eligible for a reward of up to $1,000 for information that leads to an arrest.
