--ShotSpotter, the BPD's new gunshot-detection system rounded up a gun-toting suspect Sunday night. Congratulations (we guess) to Justin Searcy, 17, of Mattapan, for being one of the first to be arrested thanks to ShotSpotter.

--The driver of the car that crashed into a tree on Blue Hill Avenue was arraigned today in his hospital bed. 21-year-old Rohan Blackwood, of Dorchester, was charged with two counts of motor vehicle homicide and DUI.

--Revere police arrested a guy who was wearing a "Free Lodie" T-shirt at a Columbus Day parade. (Derek Lodie was charged with being an accessory before the fact in the killing of Revere police officer Dan Talbot.)

Wearing a T-shirt is not a crime, but Mikey Picardi's T-shirt caused a fight. It got weird when his stepfather, Pat Starkey, came on the scene and put on the "Free Lodie" shirt to hide his handgun, and the people who were mad at his stepson turned on Starkey. Starkey, who claims he didn't even know what the shirt meant, brandished a handgun, and he will appear in Chelsea District Court.
