WORCESTER, Mass. (AP) — A Massachusetts man originally charged with murder in the fatal stabbing of another man during an attempted drug robbery has pleaded guilty to the lesser charge of manslaughter.

The Telegram & Gazette reports that Francis Arbolay is scheduled to be sentenced Sept. 17 after pleading guilty under a plea deal Wednesday to killing 23-year-old Christopher Starkweather in Gardner in January 2016.

Prosecutors say Starkweather and three others arranged a meeting to buy cocaine from Arbolay, but intended to rob him.

The 23-year-old Arbolay denied having drugs and stabbed Starkweather and another man during the ensuing struggle. The other victim survived.

Prosecutors asked for a sentence of 10 to 12 years in prison. Defense attorneys asked for four to six years.
