Authorities: Man tried to hire hit man to kill cop, 2 others

BOSTON - Federal authorities say a Massachusetts man tried to hire a hit man to kill three people, including a police officer, while he was in jail on multiple cases.

Twenty-year-old Mason Stickney pleaded not guilty Tuesday in Boston federal court to charges of using an interstate commerce facility in the commission of murder-for-hire.

Prosecutors say the hit man Stickney allegedly worked with in November was an undercover FBI agent. The alleged targets were not harmed.

It's unclear why the three people were allegedly targeted.

They say a fellow inmate at the Essex County House of Corrections had alerted authorities to the plot in October after Stickney solicited his help in the scheme, offering $10,000.

Stickney's federal public defender didn't immediately respond to an email seeking comment Tuesday.
