The police commissioner described Suiter’s assailant as, “a heartless, ruthless, soulless killer.”The manhunt for the murder suspect has encompassed a wide swath of the West Baltimore community of Harlem Park, which has been on a so-called shelter-in-place lockdown. Police cars and crime scene tape have cordoned off several blocks.The fatal shooting took place around 4:30 p.m., Nov. 15, in the 900 block of Bennett Avenue in West Baltimore, a neighborhood with a history of violence and homicide. According to police, Suiter was doing a follow up investigation to a homicide he had been working on, when he noticed a man engaged in “suspicious behavior.”“The detective approached the man, brief conversation took place, and the detective was shot in the head,” said Commissioner Kevin Davis at a press conference shortly after the shooting.Police say another officer, working in the same area, loaded the injured officer into a cruiser and started driving towards Shock Trauma, but an ambulance intercepted them and transferred Suiter to Shock Trauma.Baltimore Mayor Catherine Pugh and Baltimore City State’s Attorney Marilyn Mosby extended their prayers to Suiter’s family following the fatal shooting. “First let me ask that we just pray for the family…and let me just take a moment to remind us how dangerous our streets are at this time,” said Pugh. “We cannot have violent criminals running our streets. Too many guns on our streets…too many victims. When anyone is hurt in this city my phone rings. Everyone in each neighborhood deserves to be safe…I will be talking to the governor, we need to get control of violence in this city,” Pugh added.“This is the ultimate sacrifice to protect and serve our city. We will do our part to ensure that this perpetrator of this offense is brought to justice,” said Mosby the night of the shooting. “He deserved to come home tonight and because of the act of cowardice, he’s not.”The FBI, and the ATF are assisting Baltimore Police in the search for the suspect who is still at large, in part, by offering a $64,000 reward for any information leading to the capture of the suspect. The suspect is described as a Black male, wearing a black hoodie with a silver stripe down the back.Authorities are asking anyone with any information to text tips to 443-902-4824, call 1-866-7LOCKUP, or call Detectives at 410-396-2100.
