A Hauppauge family is searching for answers after waiting almost 30 minutes for an ambulance to show up during an emergency.

Kim Mateiko says her 84-year-old grandmother Audrey Stone was struggling to breathe when the family dialed 911 at 10:42 a.m. Sunday. Officials say they should have gotten a response from the Central Islip-Hauppauge Ambulance Corps, but no ambulance came. Suffolk police were at the scene within 7 minutes, and an officer drove Stone to the hospital after an ambulance had not arrived by 11:11.

Stone died three days later. The family says she suffered from Parkinson?s disease and an earlier arrival likely would not have saved her. They say they just want to prevent this from happening to anyone else.

The Central Islip-Hauppauge Ambulance Corps refused to comment on the specifics of the case, but say they have a policy of calling another ambulance corps if it takes more than four minutes to get a vehicle rolling.
