Good morning, Washington. Fall is rapidly decending on D.C., and that means more police activity on the campuses of area universities. Yesterday, it was George Washington University. It’s been a busy 24 hours for security personnel in Foggy Bottom: first, with the apprehension of a man who had been attempting to “touch several females while they were sleeping,” and then an ongoing investigation into a random act of violence in a residence hall. Early Friday morning, GW campus police took a man into custody at Thurston Hall on 19th and F Streets NW — with the assistance of several students who brought the individual to the security desk of the building — after another student signed the man in, then left him alone to roam the hallways unattended. (Really, dude? Not familiar with the sexual assaults which have plagued area colleges for years, eh?) In any case, kudos to those who stopped the assaulter-to-be.

Now the cops are looking for a man who apparently entered Duques Hall (22nd and G Streets for those unfamiliar with the George Washington goegraphy) at approximately 3:05 p.m. and randomly assaulted someone inside. GW’s Campus Advisory website has security footage of the person in question and police are looking for tips.

Scanning the news this morning:

>> Hector Hernandez, who shot and killed a 14-year-old on a Ride On bus last fall, received a fifty-year sentence on Thursday. Today, the Post examines how the sentencing of Hernandez — who was in the country illegally — brings to light new immigration control policies in Montgomery County, in which police now report citizenship status to immigration authorities for all violent crime.

>> Mike DeBonis caught up with the so-called “bogeyman” of the local taxi scene.

>> A 17-year-old, caught in the crossfire between a security guard and one or two gunmen on Thursday night on the 500 block of Edgewood Street NE, died on Friday afternoon. It is still unclear who fired the shot which killed young Kenyetta D. Nicholson-Stanley.
