Flames also destroyed a 2013 Lincoln MKX and a 2014 Cadillac SRX.

According to police, Patrolman Michael DeRosa was first on scene and reported flames rising 50 feet skyward from the fully-engulfed garage, spreading to the cars and several trees.

Officers roused and evacuated the owners, Barbara and Glenn McDowell, and people in neighboring homes as a precaution.

Toms River Fire Companies 1 and 2 and East Dover firefighters kept the blaze from spreading beyond the property, police said.
