Their morning started with a bit of a reunion.
Alameda County Deputy Sheriffs Tony Whittle and Sandra Williams had been partners once, but that was a long time ago. It had been at least a decade since the two were paired together on a shift.
On the morning of April 6, 2012, however, Whittle was without a partner and needed help taking two dozen prisoners from the Santa Rita Jail in Dublin to a courthouse in Oakland, and then back again. A call was put out for officers interested in overtime, and Williams answered.
Williams says it was like no time had passed between the two, and they worked together flawlessly.
That was a good thing, because before the end of the shift their teamwork would be tested, and lives would be on the line.
