Body-cam shows Chandler officers shoot, kill former firefighter accused of attacking woman

Chandler police released audio and body cam footage of the July 17 police shooting that left 44-year-old Tyson Cobb dead near Frye and Dobson roads.

Cobb was suspected of entering a home, attempting to sexually assault someone and barricading himself before being fatally shot by Chandler police officers.

According to audio of a 911 call released by police , a woman called around 3 a.m. when she heard someone screaming for help. Another caller told operators a man attempted to rape a woman and had a knife on him.

According to Det. Eva Zermeno, spokesperson with the Chandler Police Department, a man, who police identified as Cobb, entered an apartment armed with a knife and attempted to assault a woman that lived in his same complex. This is what led to the 911 calls.

Zermeno said the man threatened to commit suicide and barricaded himself with a knife when officers surrounded his home.

He then ran to the third floor of the complex, forced himself inside an apartment and barricaded himself. When officers were speaking with him, he broke a window and climbed on the roof, according to officials.

Bodycam footage shows the man on a roof when officers began to tell him to "lower the knife and get on the ground". Officers fired eight less lethal device rounds at Cobb when he refused to listen to officers, according to Zermeno.

Zermeno said the man attempted to break into another apartment but was unsuccessful.

According to Zermeno, after six minutes of attempting to negotiate with Cobb, he jumped down from the roof with the knife in his hand and moved toward officers. At least two officers fired their weapon and shot Cobb, Zermeno said.

Bodycam footage shows at least one officer shooting at Cobb when he moves towards an officer. Several shots are heard in the video.

Zermeno said the Chandler officer involved in the shooting has been with the department one year and the SWAT officer involved has been with the department for 16 years.

Officials said Cobb died at the hospital due to his injuries.

Internal and criminal investigations into the shooting are currently underway, Zermeno said.
