TAMPA, Fla. (CBS/AP)– Police say a Florida man asking if a bulletproof vest “still worked” was fatally shot by his cousin.

A Tampa Police report says 23-year-old Joaquin Mendez put on the vest late Saturday and “wondered aloud whether it still worked.”

According to a witness, Mendez sat in a chair and put on the vest. His cousin, 24-year-old Alexandro Garibaldi, took out a handgun and said “Let’s see,” CBS affiliate WTSP reported.

Officers found Mendez outside the house with a gunshot wound in his chest. Mendez died at a hospital.

According to the report, Garibaldi initially told officers he found his wounded cousin after hearing a gunshot. However, police say a witness described Garibaldi shooting Mendez.

The vest was found in the house with a projectile entrance hole, WTSP reported.

Garibaldi was held Sunday without bond on a manslaughter charge. Hillsborough County jail records didn’t show whether he had an attorney.
