The family of 43-year-old #WilliamGreen gathered Tuesday morning near where Green was shot & killed by a Prince George’s County Police officer last night. They are angry and demanding answers. “We want to know why our loved one was brutally shot in a police car, handcuffed, seatbelted, & in the front seat,” said Sandra Mathis, William Green’s fiancé. Police say they found Green at about 9 p.m. Monday night on Winston Street in Temple Hills. They were responding to 911 calls about a car slamming into parked vehicles. By the time police arrived, Green had passed out behind the wheel. Police say that Green hit a total of six cars before he passed out behind the wheel. Officers suspected he was on PCP and neighbors watched while he was put in handcuffs. PGPD now say they "do not believe PCP was involved." The officer who shot Green, Ofc. Michael Owen Jr., was arrested at his home and taken into custody, then charged with second degree murder and manslaughter. PGPD addressed those charges at a Tuesday press conference, which you can watch below. ABC7 News has learned Owen is a 10-year veteran and this is his third shooting incident, including one in 2011 when he shot & killed an armed man. At some point after Green's arrest, sources say that Owen got in the driver’s seat next to Green and radioed that Green needed to use a bathroom. Those sources say Owen & Green then got into some sort of altercation, & the officer shot Green 7 times. “They shot my son & it’s not right,” Green’s grief-stricken mother, Brenda Green, said. “How you gonna shoot somebody sitting in a front seat of a car in handcuffs & with a seat belt on? Why would you do that?” Green’s fiancé said over & over that it makes no sense. “We have questions that’s not being answered. We want to get to the bottom of this.” William Green’s family says there can be no good explanation for this shooting. “I have concluded that what happened last night is a crime,” said Chief Hank Stawinski. As for Green's presence in the front seat: #PGPD officers follow a directive when it comes to transporting arrestees that specifies what seat they sit in.
