Brookfield Police and EMS helped an elderly woman change a flat tire Saturday.  The woman pulled into the Brookfield Volunteer Fire Company Center Station on Route 133 in the afternoon.  The EMS crew from Vintech Management Service, and an off duty Brookfield Police official, jumped into action and changed her tire and got the woman on her way in short order.  Fire officials say the EMS team is mission driven and community service minded, even if it means becoming a pit crew for a stranded motorist.
