Grechario Tyzavian Mack, 30

Grechario Tyzavian Mack, a 30-year-old black man, was shot and killed by Los Angeles Police on Tuesday, April 10, at the Baldwin Hills Crenshaw Plaza mall, at 3650 W. Martin Luther King Jr. Blvd., according to Los Angeles County coroner’s records.

Officers responded to reports of a man with a knife in the mall about 5:40 p.m., said LAPD Officer Mike Lopez.

Officers saw the man “aggressively” waving a knife, according to a news release from the department. Police said officers began to talk to the man, later identified as Mack, and repeatedly told him to put the knife down.

Mack was “very agitated, and it appeared that he was possibly under the influence or was going through a mental health crisis,” police said.

Mack began to run toward shoppers with the knife in his hand, and officers shot at him, according to the department. He was pronounced dead at the scene and a knife was recovered.

Video recorded by a witness and obtained by CBS-TV Channel 2 showed a man running before four gunshots are heard. A witness to the shooting said he was eating with his family at Americana Buffet & Grill when he noticed the man walking around near the escalators.

The witness, who asked to remain anonymous but provided a video that captured part of the encounter, said he saw a man holding a knife at his waistband. Soon after, two officers drove up and entered the mall, while one drew his gun and the other pulled out a Taser.

Investigators with the LAPD’s Force Investigation Division were canvassing the scene and speaking with witnesses.

Officials with the Los Angeles County district attorney’s office and the Office of Inspector General also responded, as is customary with police shootings.

Mack was the eighth person shot by on-duty LAPD officers in 2018. Six of those eight died.

The LAPD identified the officers involved as Sgt. I Ryan Lee and Police Officer II Martin Robles, both of the Southwest Division.
