WOBURN, MASS. (WHDH) - A man was charged Tuesday with manslaughter in connection with the death of a 15-year-old Cambridge girl who smacked her head after being thrown to the ground last summer.
An indictment charging Isaias Plaza, 19, of Boston, with manslaughter and assault and battery resulting in serious injury was unsealed in Middlesex Superior Court.
Robinson was heading down Cambridge Street to a friend’s house on the evening of July 22, 2018, when Plaza allegedly attacked her.
Investigators say Robinson seriously injured her head when Plaza shoved her down. She was rushed to an area hospital, where she later died.
Plaza allegedly fled the scene on a bicycle. Witnesses told investigators that he was wearing jeans and black sneakers with white soles.
Prosecutors say Plaza then burned the clothes described by witnesses at the time of the assault in an effort to avoid being connected to Robinson’s death.
Plaza and Robinson are said to have known each other and previously shared a group of friends but the two “had a falling out” in the weeks preceding the attack.
Robinson was a student at Cambridge Rindge and Latin. She was heading into her sophomore year and set to turn 16.
Plaza waived his right to an arraignment and was ordered held without bail.
A not guilty plea was entered on his behalf.
