first there are a series of small repairs, including a jalopy of a furnace. then during the 7:00 showing of "despicable me ii". >> i got a phone call from one of the girls that people were acting weird. there was a carbon monoxide issue. >> it turns out the berwick did not have carbon monoxide detectors. and the cause of the accident -- pigeons had gotten caught in a furnace pipe. >> my husband came down before i did. he had already done a quick sweep of the premises, and he about passed out. so i was like, oh, my gosh. what is happening. i was terrified. >> what was happening? people falling out of the theater? >> some people had carbon monoxide poisoning, and they were passing out.
