Worcester District Attorney Joseph Early Jr. once again appealed to the public during Thursday’s news conference, asking anyone who may have any information about Marcotte’s homicide come forward.

Early told reporters detectives are certain Marcotte’s attacker was a man, and that he probably walked away from the slaying battered and cut up.

Marcotte, who lived in New York City but was visiting her mother over the weekend, was found dead Sunday night, several hours after she went for a run.

Her body was recovered from a wooded area about a half mile from her mother’s home. Marcotte’s body was found unclothed with burn marks, according to investigators.

Police have received hundreds of tips about the killing, but say they’ve yet to identify any possible suspects.

Investigators also can not say with certainty whether she was targeted or the victim of a random attack.

Early said investigators are also interested in speaking to anyone who may have seen any vehicles driving or parked near where Marcotte’s body was found. Anyone with information is asked to call the Massachusetts State Police tipline at (508) 453-7589.

Marcotte visited Princeton often to see her family. She grew up in nearby Leominster, and attended the Bancroft School in Worcester before graduating from Boston University in 2011.

Marcotte’s death bears eerie similarities to the killing of a New York City woman, who was strangled and sexually assaulted while on a run through a Queens park last week.

Like Marcotte, 30-year-old Karina Vetrano was killed while running alone in a secluded area.
