WORCESTER, Mass. — A security guard at a Worcester rooming house who shot and killed the facility’s janitor has been sentenced to up to 20 years in prison, after which he faces deportation.

Howard Penn was sentenced Wednesday, two days after he was convicted of voluntary manslaughter for shooting Lloyd Worster in the back after the pair had a fight at the Albion rooming house in January 2014.

Defense attorneys say the shooting was in self-defense because Worster had threatened to kill Penn.

The Telegram & Gazette (http://bit.ly/2bkCNqI ) reports that the 56-year-old Penn’s lawyer asked for a lesser sentence because of his client’s health problems, including kidney failure, which cannot be properly cared for behind bars.

The defense attorney also says his client faces deportation to his native Turks and Caicos Islands.
