A Boston police officer involved in a March accident that left an 18-year-old woman dead will not be charged in the incident.

Investigators have determined that Sgt. Warren Hoppie, who was off-duty at the time, could not have avoided striking Katelisa Etienne, who was on foot, CBS Boston reported. The incident took place near the intersection of Brush Hill and Aberdeen roads around 3:30 p.m. on March 9.

An investigation found that a parked vehicle obscured drivers’ ability to see Etienne as she walked onto the roadway, WHDH stated.


State Police said that Hoppie was not speeding, on his cellphone or under the influence at the time of the crash, according to CBS Boston.

After the incident, Etienne, a senior at Milton High School, was taken to Boston Medical Center and pronounced dead, CBS Boston added.
