A man who tried to hire someone to kill Mount Vernon’s police chief has been sentenced to 70 years in a federal prison.

In the summer of 2011, 30-year-old Lorenzo Harris-Thompson of Mount Vernon pled guilty to illegal possession of a firearm. While he was in jail, waiting to be sentenced, Harris-Thompson tried to arrange a hit on Mount Vernon’s police chief. The aim, apparently, was to keep the police chief from testifying at Harris-Thompson’s sentencing hearing. But the hit man Harris-Thompson was trying to hire turned out to be an undercover cop.

In the summer of 2012, Harris-Thompson was convicted of attempted murder in that murder-for-hire scheme. His 70-year sentence was handed down this week.
