An 8-months-pregnant teacher's aide was shot while sitting inside her car in Springfield Gardens yesterday. Leba Toussaint was talking to a friend who had recently gotten out of prison, and was shot in the shoulder by someone firing from a passing green Acura. Her father believes the bullet was intended for her friend, though he was unharmed in the shooting. He told the Daily News, "She's going to be okay. They have to be careful with anything they do because she's pregnant." Police couldn't confirm that the ex-con was the intended target of the shooting.
