A man wanted in connection with using students from a Carmel Valley high school to sell drugs is still at-large and he may be armed.
Crime Stoppers is offering up to a $1,000 reward for any information that leads to the arrest of William "John" Sipperley.
Sipperley lived together with his companion Kimberly Quach, who was arrested for allegedly selling or offering suboxone and Xanax to minors from Jan. 1 to September, as well as giving at least 10 teens marijuana to sell, package or transport, according to a 37-count criminal complaint.
If convicted, Quach could face 60 years in prison.
NBC 7 previously learned the San Diego County District Attorney's Office had issued an arrest warrant for Sipperley on Nov. 1.
Sipperley and Quach were living together, according to the arrest warrant. He grew marijuana inside the house in the summer of 2016 and began selling that marijuana, along with Quach and her daughter.
He also had several run-ins with the police in the past, court records showed.
Sipperley has an outstanding felony warrant for his arrest, according to Crime Stoppers.
Investigators believe he may have left San Diego and may be hiding in Oregon, Hawaii or the Las Vegas area.
He is 50-year-old, 5 foot 9 inches tall, 180 pounds with brown hair and brown eyes. Investigators say he may be driving a white 2007 Honda with a California license plate of 7PES884.
Anyone with information is asked to call Crime Stoppers at (888)580-8477.
