SPRINGFIELD, Mass. (AP) — The medical examiner who conducted autopsies on the bodies of three women found in a Massachusetts home concluded they had been assaulted, but could not identify a specific medical cause of death for any of them.

The women — Kayla Escalante, America Lyden, and Ernestine Ryans — were found at the Springfield home of Stewart Weldon in May.

Weldon faces murder and rape charges in connection with the deaths.

The victims' death certificates obtained by Masslive.com listed the cause of death as "homicidal violence." They also say while the dates, times and locations of their injuries are unknown, they were caused by assault.

Weldon is being held on $2 million bail and is scheduled for arraignment on Monday.

His attorney has said Weldon is looking forward to defending himself in court.
