A southwest Florida community mourned the five teenagers who were killed in a crash and found in a submerged car in a retention pond after their shift at Texas Roadhouse restaurant earlier this week.

The five teenagers were killed Sunday after they apparently lost control of a Kia sedan and crashed into a retention pond near a Topgolf, said Fort Myers Police. Officers found the victims Monday in the submerged car and all five were pronounced dead at the scene.

The incident marks the highest number of fatalities seen in a traffic incident in southwest Florida since March 2011, according to Florida Department of Transportation officials. Investigators believe speed was a factor in the fatal crash.

Police identified the victims as Eric Paul, 19; Jackson Eyre, 18; Amanda Ferguson, 18; Breanna Coleman, 18; and Jesus Salinas, 18. Paul, Eyre, Coleman, and Salinas were recent high school graduates while Ferguson had graduated last year and was attending college.

Four of the teenagers – Coleman, Paul, Eyre and Ferguson – had wrapped up their day of work at a nearby Texas Roadhouse restaurant, and were accompanied by Coleman’s boyfriend Salinas at the time of the crash.

Texas Roadhouse offered its condolences and also closed its doors Monday to host family and friends for a dinner in the victims’ memory.

“The environment with Texas Roadhouse, we were all young, we were all teenagers, we were all like best friends,” said Lylah Law, a former Texas Roadhouse employee who worked alongside Eyre, Paul, and Ferguson for about a year.
