Dean Barker, a 59-year-old taxi driver from Merced, California, was shot dead on January 5, 2015 after picking up a fare. Barker, active in his community and a member of Jehovah’s Witnesses, was reportedly shot in the head three times when the passengers — later identified as Joseph Castrillo and Dante Woods — reached their destination. The first shot caused severe damage and witnesses said subsequent shots left him unrecognizable.

Police arrested Joseph Castrillo and Dante Woods and charged them with first-degree murder. At trial, Dante Woods testified that he saw Castrillo pull out a gun and shoot Barker, and another witness testified that Castrillo had bragged about the killing soon after it happened. Testimony about the mechanics of firing the weapon three times was introduced to support the prosecution’s case.

The family said Barker’s death left a deep void and they have struggled to cope with the loss. Does anyone have information about Dean’s last shift or the events leading up to that January 5 pickup?
