"Ay, yo, here comes Time Out," a young man on the opposite corner yelled, using a neighborhood term for police.
Gray swore, taking off on foot as the officers began hot-stepping on their pedals to catch up. One officer jumped off his bike to chase Gray on foot, police said.
"That was the last time I seen that man moving," said Washington, 48.
The 45-minute mystery of Freddie Gray's death
Investigators with the city police and other agencies are still trying to recreate the events of the next 45 minutes, during which Gray sustained a severe and ultimately fatal spinal cord injury while in police custody.
But in its own investigation, The Baltimore Sun found that police missed the opportunity to examine some evidence that could have shed light on events. For example, by the time police canvassed one neighborhood looking for video from security cameras, a convenience store camera pointed at a key intersection had already taped over its recordings of that morning.
