A Pennsylvania couple tragically lost their lives while vacationing in Florida with their six children, after being caught in a rip current.

Brian Warter, 51, and Erica Wishart, 48, were swimming with two of their teenage children on Hutchinson Island on June 20 when the situation turned perilous.

While the teenagers survived, their parents were unable to escape the rough ocean waters.

The Martin County Sheriff’s Office released a statement detailing the harrowing incident. According to the release, the teenagers made valiant efforts to save their parents but were ultimately unable to overcome the powerful current. Emergency services were quickly dispatched, and rescue efforts were initiated. Unfortunately, despite being transported to a nearby hospital, both Brian and Erica were pronounced dead by medical staff.

Phillyburbs.com reported that the water conditions were notoriously dangerous that Tuesday afternoon, with red flags flying at the beach to warn swimmers of the hazardous riptide conditions, according to Martin County Fire Rescue representative Cory Pippen. These flags are intended to alert beachgoers of potential dangers in the water, such as strong rip currents.

Larry Warter, Brian’s father, shared with CBS 12 News that his son and Erica had been in a relationship for over a year and were engaged to be married. Erica was a mother of four, while Brian was a father of two. The couple had planned to wait until all of their children finished college before tying the knot. Their trip to Stuart, Florida, was a significant milestone for them.

“They were so thrilled, they couldn’t see straight about going down,” Larry Warter recounted. “This was the first time. This was the experiment. They had all six of their kids together. They had been planning it for over a month.”
