Officials have identified two people who were found dead Sunday at a Peabody residence.
Mark Greenlaw, 37, and Jennifer O’Connor, 39, were both believed to be residents of the 19 Farm Ave. home, according to Carrie Kimball-Monahan, a spokeswoman for the Essex District Attorney. Greenlaw and O’Connor were dating, Kimball-Monahan said in a news release.
Officials say they are seeking two suspects in the killings, which rattled the neighborhood.
When police arrived at the scene, they found a crime scene so “messy” that it was initially difficult to determine how many bodies were in the house, said Kimball-Monahan.
Police requested X-ray equipment from the state fire marshal’s office to help make an accurate body count, Monahan said.
State Police learned about the deaths at about 11:30 p.m. Saturday when a woman who had been inside the home arrived at their barracks in Danvers, Monahan said.
The woman had fled the home and flagged down a vehicle that brought her to the barracks. Troopers then went to the home and called for a police dog, Monahan said.
Based on a statement the woman made to police at the barracks, she said, it appears that the people involved in the crime knew one another.
Police Chief Thomas Griffin said in a news conference at the scene that the home was known to police, according to video of the conference shown on WCVB-TV (Channel 5).
“We’ve been here a number of different times for all kinds of different incidents,” Griffin said. “It wouldn’t really be fair to characterize them as any one particular way.”
