BRIDGEPORT - Some Bridgeport residents are calling for a state investigation into the deaths of two puppies at the city's animal shelter after they fell down a drain last week.Those in favor of the probe say rescuers were held up from cutting through the floor to save the animals because they never got approval from the city. A former Bridgeport employee says people offered to fix the floor for free if they were allowed to cut through it. He also says the decision to use a high-pressured hose to push the puppies through the sewer was inhumane. A spokesperson for the mayor's office says the incident is an unfortunate situation but they have no other comment at this time.
