St. Louis police shoot and kill man armed with knife

St. Louis police say they had no option but to use deadly force when a suspect charged them while holding a knife, officials said Saturday.

Two St. Louis police officers shot and killed an armed suspect after he charged them while holding a knife, officials said in a statement issued early on Saturday.

Police posted what they said was body cam video of the Friday night shooting within hours of the incident.

"The officers resorted to less lethal force to try and bring the incident to a safe conclusion with no loss of life, but this individual made the decision to refuse these attempts, and charge at officers with a deadly weapon."'

Police in Missouri and around the country have been under intense pressure since the death of Michael Brown, an unarmed black teen who was shot and killed by cops in Ferguson, Missouri, on August 9, 2014. Brown's death sparked nationwide protests and increased scrutiny of shootings involving police and minorities.

Police had no option but use deadly force, according to a statement by Chief of Police Jon Belmar.

"The officers resorted to less lethal force to try and bring the incident to a safe conclusion with no loss of life, but this individual made the decision to refuse these attempts, and charge at officers with a deadly weapon," he said.

In the statement, police said they responded to a call from a woman who asked that her son, Thaddeus McCarroll, 23, be removed from her home. McCarroll, who was talking about going on a "journey" and mentioned "black revolution," had allegedly locked her out of the house and was walking around the house with several knives and a Samurai sword.

At 10:30 p.m. local time, police requested support from the force's Tactical Operations Unit, which began to negotiate with McCarroll, police said.

"After approximately one hour of negotiations, the subject exited the residence armed with a knife in one hand, and a Bible in the other," according to police. Officers then tried to get McCarroll to drop the knife, firing a "less lethal round" at him in an attempt to disarm him and ordering him to speak with them without holding the knife — but that didn't work, police said.

"The subject immediately charged the officers at a full run with the knife still in hand," police added. "Fearing for their safety, two officers shot the subject multiple times."

Police in Missouri and around the country have been under intense pressure to be transparent since the death of Michael Brown, an unarmed black teen who was shot and killed by a white officer in the St. Louis suburb of Ferguson on Aug. 9, 2014. Brown's death sparked nationwide protests and increased scrutiny of shootings involving police and minorities.
