Anyone missing a pet boa constrictor? Yesterday, Emergency Service cop Michael D'Alessandro captured a massive boa constrictor that was seen on a bridge in Springfield Park in Queens. Officers said they didn't know the exact measurements of the snake, but judging from the Post photo it has to be at least five feet, right? One witness said, "I've seen strange creatures around here, but that's scary." The boa was put in a bag and brought to a local vet. At least it wasn't in anyone's toilet this time.
