Police have identified the woman killed when she was struck by a tow truck in the Langley Park area Saturday night as 76-year-old Irma Glover, authorities said Monday.

Glover, of Takoma Park, had stepped into the eastbound lanes of University Boulevard when she was hit by a tow truck leaving the parking lot of a Pep Boys auto parts shop in the 1800 block of the roadway, said Cpl. Larry Johnson, a Prince George’s County police spokesman. He said another vehicle — an older model, four-door black Toyota — is then believed to have run over the woman’s clothing, and police are looking for the driver of that vehicle as a witness to the incident.

The crash occurred about 8:40 p.m.

Johnson said that Glover was not in a crosswalk when she was struck, and police do not believe the tow truck’s driver was drinking or speeding at the time of the collision. Glover was one of three people killed in separate incidents in Prince George’s over the weekend.
