A carjacking, a robbery, several shootings and even a homicide.

These were just some of the crimes that law enforcement sources in St. Louis said may have also been committed by a man who ambushed and seriously injured one of their own.

George P. Bush, III, 19, was killed early Monday in a shootout with police in the 6500 block of Smiley Avenue, near Arsenal and Interstate 44.

The confrontation followed their pursuit of him for the shooting of a 46-year-old veteran sergeant of the St. Louis Metropolitan Police Department on Sunday evening.

Officials said Bush shot the officer, who’s been on the force for 20 years, twice in the face while the officer was sitting alone in his marked SUV at Hampton and Pernod waiting for a red light to turn. The officer was released from the hospital and police said he is expected to survive his injuries.

But sources told NewsChannel 5 Bush was already a likely suspect in several other violent felonies at the time of his death.

St. Louis County Police confirmed he was being investigated for possible involvement in the robbery and shooting of a woman at the Denny’s in Fenton on November 11. The woman was shot in the chest even though she complied with the suspect’s demands.

City police also believe Bush had something to do with the shooting death of Joseph Hults, 52. The locksmith was found inside a burned up van on Poepping on November 19.

That same day, county police said Bush might have been involved in the robbery, shooting and carjacking of a 27-year-old man on Creek View Trail in Affton.

Sources said their investigation into the teen continues despite his death.

He has been linked to an unknown number of associates in south city, who are also considered dangerous and may have had a role in some of the aforementioned crimes.

It’s one of the aspects detectives in the city and county are looking at, according to sources.

St. Louis Police Chief Sam Dotson said Monday, “We’re looking at a lot of leads right now. We’re going to do our due diligence and make sure we understand everything.”
