It was another one of those violent weekends in Baltimore -- at least 18 wounded, several dead, including a 4-year-old boy who apparently got hold of a gun and fatally shot himself in the head. The latest in this spate of violence occurred Sunday night in Northwest Baltimore, when three people were shot.

Baltimore police officials have called a news conference for late this morning to discuss the violence; hopefully we'll learn whether any of it is connected. It came in two spurts -- Friday night, which included the wounding a city police officer, and throughout the day and night on Sunday.

The violence included, but is not limited to, a fatal shooting on Frankford Avenue, a man fatally stabbed at a West Baltimore gas station, and a fatal shooting in Pigtown. Check back for more details later today.

Meanwhile, a Maryland State Police trooper shot a New Jersey man in the hand after a chase Sunday night that started with a stolen car spotted in the Fort McHenry Tunnel and ended up further south on I-95 in Prince George's County. See more details.
