One of three men who led Boston police on a dramatic roof top chase in Dorchester over the weekend had prior drug charges against him dismissed because the state chemist in that case was Annie Dookhan, who is alleged to have tampered with substances she tested, authorities said.
Maykor Baez, 20, of Roslindale, pleaded not guilty at his arraignment in Dorchester District Court on Monday to drug and gun charges stemming from the chase early Saturday, Suffolk District Attorney Daniel F. Conley’s office said.

Fantastic police work. Second time in a week we hear of heroic actions above and beyond the call of duty by the Boston Police. All this while they are 3 years without a contract and get paid $15,000 a year less than a Boston Firefighter, $20,000 a year less than State Troopers, and less than Cambridge, Brookline, and Quincy Police.
Just saw the video of the apartments this cop made the jump from. If you haven't seen it, it's on all the TV stations news websites. Again, heroic actions. Not exactly running a speed trap on 93 with a shiny take home cruiser making $20,000 a year more.
