A woman was injured Feb. 18 when her car struck a tree at a high rate of speed, then a house and flipped onto its side.

The crash occurred at about 12:30 p.m. that day on Main Street near the intersection of Laurel Street.

Dale Malmstrom, 65, of Rockland, was operating her 2007 Jeep Grand Cherokee north on Main Street. According to police, she suffered a medical emergency, which caused her to lose control of the vehicle.

She went from the oncoming lane back to the other lane, rolling the vehicle which struck a stop sign, a large tree, and the house at 179 Main St. The impact knocked down the tree, destroyed the vehicle, and caused significant structural damage to the house owned by Daniel and Barbara Courant.

Malmstrom, an adult passenger and two juvenile passengers were taken to Pen Bay Medical Center in Rockport for non-life threatening injuries. All occupants were wearing seatbelts and airbags were activated.

Assisting agencies were Rockland Fire/emergency medical services, Thomaston EMS, Rockland Public Services and Rockland Code Enforcement Office.  Central Maine Power also responded because power was lost in the immediate area.

Sgt. Ken Smith said speed was also a factor in the crash.
