A Florida Highway Patrol trooper spotted a car parked along the interstate with its hazard lights on around 1:30am Saturday and stopped to investigate. He found a couple dead on the side of the road nearby and their three children still strapped into their car seats, the Daytona Beach News-Journal reports. Authorities say the couple had a history of drug abuse, and it appears 32-year-old Daniel Kelsey may have died from an overdose. Questions remain about the cause of death for 30-year-old Heather Kelsey, and authorities are waiting on the results of an autopsy.
The couple's three children—ages 2, 1, and an infant—were unharmed. Authorities don't believe the car had been on the side of road for longer than 30 minutes. The children are staying with relatives. There were no signs of foul play or trauma, though it remains unclear why Daniel and Heather Kelsey got out of the car before dying, CBS News reports. They had been married for nearly six years. "It boggles me," a family friend tells WFTV. "I'm blown away by it. I don't want to believe it." (Read more Florida stories.)
