A Pittsfield man foiled a murder plot against him when he interrupted three men in the process of robbing his home Friday, according to police.

According to a police affidavit filed in court, Edward Rich's arrival home on Friday afternoon busted a plan for his murder concocted by a former employee who had dated his daughter.

That suspect, 22-year-old Jerome Thompson of Concord, was arraigned Monday along with two alleged accomplices to face a slate of criminal charges including conspiracy to commit murder, which carries a punishment of 15 to 30 years in prison.

Police said the three men planned to steal guns from Rich's Pittsfield home, then storm his auto repair business and kill Rich and anyone else present.

Police said Thompson wanted Rich dead because the older man had caught him stealing from the business.

Bail for Thompson, 21-year-old Kyle Weeks of Pittsfield and 21-year-old Jason Cheney of Pittsfield, was set at $100,000 each.

The three are due back in court for probable cause hearings in early November.
