A body was discovered Tuesday morning in a wooded area near the corner of Amity Street and University Drive, believed to be that of a local woman missing since Friday night.

Marissa Jackson, 26, of Amherst was reported missing since Friday night, according to a statement from the Northwestern District Attorney’s Office. She was last seen walking near the area of her Belchertown Road apartment at approximately 10:30 p.m. Friday, according an APD press release.

Various officials from the Massachusetts State Police, Amherst Police Department and the University of Massachusetts Police Department were in and out of the crime scene, which was roped off with yellow police tape, for at least four hours Tuesday morning.

Jackson’s family members gathered in a parking lot near the scene while police investigated, hugging and crying.

The death remains under investigation by state police, APD and UMPD, according to the District Attorney’s Office. The cause of death will be determined by the Office of the Chief Medial Examiner.

UPDATE: 6 p.m.

UMass Police sent an email to the campus community late Tuesday afternoon saying that there is no information to indicate a danger to the public. Based on available records, the email said, Jackson was not a UMass student or employee.
