WINTER GARDEN, Fla. — Authorities say a Winter Garden woman returned home to find a sport utility vehicle and two dead bodies in her backyard swimming pool.

Police say it appears 67-year-old Rafael Cabrera and his 87-year-old mother-in-law were heading to a house next door Friday afternoon, where his wife was baby-sitting. A driveway lines up directly with the pool, and it appears Cabrera failed to stop. There were no skid marks or signs of speeding.
