DORCHESTER, Mass. (AP) — A 19-year-old aspiring model was struck and killed by a dump truck when he was riding a bicycle delivering food in Boston.

Authorities say Antawani Wright-Davis was working for the restaurant delivery service DoorDash when the truck backed over him Friday afternoon.

Rosemarie Davis says her son was working two jobs as he worked on his dream of becoming a professional model.

A professional photographer tells The Boston Globe the two were planning on doing an editorial shoot Saturday. A vigil for Wright-Davis was held Sunday afternoon instead.

A bicycle painted white in his memory is now stationed outside his mother's apartment in Dorchester.

No charged have been filed against the truck driver. Police say the teen's death is still under investigation.
