The year tasers became deadly: A look at three police encounters in San Mateo County

Chinedu Valentine Okobi, the 36-year-old son of Nigerian immigrants, was unarmed when he was stopped by a San Mateo County sheriff’s deputy in Millbrae on Oct. 3.

Okobi, who grew up in San Francisco, had been walking in the 1300 block of El Camino Real at about 1 p.m. that day. The interaction between Okobi and the deputy quickly turned violent and as more deputies arrived, at least one deployed a Taser stun gun. Okobi died from his injuries.
