Online cannabis advertising platform Weedmaps and a Southern California vape shop have been targeted with a wrongful death lawsuit in civil court by a mother who claims both are to blame in the shooting death of her son.

According to Law360.com, the lawsuit alleges that both companies are complicit in the death of 19-year-old William Benjamin Harris IV, who was fatally shot in June 2019 by cannabis delivery worker David Christopher Gregorich.

Gregorich, an employee at Altadena vape shop Universal Stop, has been charged with several crimes in the case, including murder, and has pleaded not guilty.

Gregorich’s attorney told Law360 the employee opened fire because he thought he was being robbed when Harris approached his car.
