An Easthampton man accused of killing his girlfriend has been indicted by a Hampshire County grand jury.

Ryan Welch was indicted on a murder charge Tuesday in connection with the Feb. 20 slaying of Jessica Ann Pripstein.

Police received a 911 call from the 39-year-old Pripstein in which she said her boyfriend was trying to kill her before the call cut off.

An autopsy determined she died from a “sharp-force injury’’ to her neck.

Welch was arrested the next day at a hospital where he was treated for a self-inflicted wound.

His Superior Court arraignment is scheduled for Friday.

The 36-year-old Welch is being held without bail after pleading not guilty in district court.

His lawyer said Welch has a history of mental illness and takes various prescription medications.
