The incident began at 1:12 a.m. [Tuesday 06SEP] at the College Park Marriott Hotel and Conference Center, police said.
From Washington Post:
Apparently a group of robbers made off with three safes (?) and during the course of the robbery, the [unarmed] security guard was shot.

insertcoffee this is awful! Glad to see the security guards held the defensive line as best they could. From the article, it appears this happened last month... I noted that September 10th is today, Saturday, and not Tuesday the 10th as suggested. At any rate, this is a frightening story. Glad to hear that it would appear that everyone will be ok. I hope the capture of one suspect leads to the apprehension of the other two.
