Boston Police report the following:

Two teens, 14 and 18, were arrested on charges they used a gun to beat up a pizza-delivery guy, whom they also allegedly kicked in the stomach before they took his pizza on Westview Street in Dorchester. Unfortunately for this pair of alleged hoodlets, they did so last night, so police followed their footprints in the snow to a nearby building and arrested them:

... Officers gained entry to the back of 190 Westview St. and there observed wet footprints leading to two apartments. While inside the building, officers also found pizza crust leading from the second floor to the third floor landing. ...

A 15-year-old on King Street, also in Dorchester, wound up in jail after his mother called police to report a gun in their apartment. When police arrived, they say they found the kid packing the gun in his pocket.

A 17-year-old from Brookline is charged with running down a woman around 2 a.m. today at 218 Commonwealth Ave. The woman was found unconscious and was brought to Mass. General in critical condition. The teenager will be arraigned Monday on charges of OUI, operating without a license and operating under the influence of alcohol resulting in serious bodily injury.
