A woman whose sport utility vehicle crashed into a Macomb County pond was trapped inside for two days before a passing motorist spotted the wreck, authorities said.

Jennifer Bova, 21, of nearby Armada Township, was airlifted to Beaumont Hospital in Royal Oak Friday after a state trooper went into the pond and found her seriously injured inside the partially submerged 1991 Chevrolet Suburban.

"We could use everybody's prayers," her father, Joe Bova, told the Detroit Free Press for a Saturday story.

He said the last time he heard from his daughter was Wednesday night. She called on her cell phone to say she left church and was headed to her grandmother's house. On the way, she apparently drove off a road, down an embankment, into a tree and finally into the water.

The family left 13 increasingly frantic messages on Bova's cell phone but never received a response, The Macomb Daily of Mount Clemens reported.

Police told Bova's family she suffered bleeding in the brain, multiple fractures to her pelvis, arm, face and a broken femur.

Bova was in critical condition Saturday, according to Beaumont spokeswoman Joy Korri.

Troopers were dispatched Friday morning after a truck driver spotted Bova's car in the pond, The Detroit News reported.
