>> District officials cut the ribbon yesterday on a new $210 million forensic crime laboratory that was first planned six years ago. The facility on E Street Southwest will house 270 employees who will conduct autopsies, bioterrorism investigations, public health studies and maintain fingerprint and DNA databases. “This building and these experts will allow us to stay in front of the curve,” Paul Quander, the deputy mayor for public safety, told The Washington Examiner.

>> A couple dozen protesters, hoisting signs and spewing vulgarity-laced chants, marched through downtown D.C. for much of the day Monday to mark the first anniversary of the Occupy D.C. movement. While the march was mostly peaceful, there was at least one tense moment, the Post reports, when one demonstrator wedged a wooden pole under a police vehicle’s bumper. When the officer driving the truck moved forward a bit, the pole snapped, prompting the officer hop out of the car.

>> Though LivingSocial’s offer to pay to keep Metro open late during the Nationals’ upcoming playoff games has an ick factor, D.C. Council Chairman Phil Mendelson doesn’t feel it. He’s glad the daily deals company stepped forward, and he thinks it’ll get all its money back, too. “If the playoff games sell out, my guess is they will sell out, then there will be enough ridership on Metro there will not be a cost,” Mendelson said at a news conference, WAMU reports.
