How do people leave their homes in the morning? Since Thursday, three people have been killed by vehicles in Brooklyn.

Early this morning, the Post reports that "one person was killed and two others were injured" when a van hit them at Avenue U and East 33rd Street in Marine Park. A witness said, "I was in my basement when I heard a big bang. First I heard the hand on the horn and then I heard a bunch of girls screaming." Then she "saw a boy dead on the street." The driver stayed at the scene; it's unclear if he/she was charged.

Yesterday morning, a pedestrian on New York Avenue was killed by a city Sanitation truck, whose driver had failed to yield. The 57-year-old victim was in the crosswalk when the truck was turning left. The driver was issued a ticket.

And on Thursday morning, a 59-year-old woman was killed while trying to cross Adams Street at Joralemon Street in downtown Brooklyn. A witness told the Daily News, "The light turned yellow and instead of yielding, he tried to catch the light. Everybody tries to catch the light. But that's the wrong area to do that." The investigation is continuing.
