A San Francisco Bay Area golf coach accused of molesting three boys tried to hire a hit man to have them killed, prosecutors said.

The Alameda County District Attorney's Office has charged 32-year-old Andrew Michael Nisbet with three counts of solicitation of murder. Nisbet already was facing dozens of molestation charges.

The Livermore golf coach exchanged letters with a confidential informant in which he indicated he wanted the victims killed and discussed the price, prosecutors said Tuesday. They said Nisbet later met with an undercover agent posing as a hit man to discuss the killings.

The agent allegedly made a shooting motion with his hand and told Nisbet he would make it seem like a robbery.

"It appears from Nisbet's letters to and from the (confidential informant) as well as his conversation with (the undercover inspector), he is serious about having the victims killed in exchange for money," Jeff McCort, with the district attorney's office, wrote in a document seeking a warrantless arrest.

A call to Nisbet's attorney, Timothy Rien, by the Contra Costa Times (http://bit.ly/1hVZZTm) on Tuesday was not returned.

Nisbet was a well-respected golf instructor. His arrest last year came a day before he was to receive the PGA's Northern California Section 2013 Junior Golf Leader Award for his work with young golfers.

Nisbet is accused of molesting three students between the ages of 12 and 17. The abuse took place between 2007 and 2012, according to prosecutors.

Livermore is a suburb about 45 miles east of San Francisco.
