Palmetto Ridge High School two-time state champion wrestler and starting linebacker Colby Singletary died in a single-car crash on Saturday evening.

Singletary, 18, was driving west on Golden Gate Boulevard near 31st Street SW when his 2016 Kia Sportage drove over the median and struck a tree at 5:38 p.m., according to the Florida Highway Patrol report. Singletary was not wearing a seat belt and alcohol was not involved, according to the report.

Passenger Alexis Renner, 17, of Naples is in serious condition and was wearing a seat belt, according to the report. She's being treated at the Golisano Children's Hospital.

As the news hit social media Saturday night, Singletary's friends paid tribute.

"I truly can't believe it," former Palmetto Ridge wrestler and fellow two-time state champion Joey Nadotti wrote in a Facebook post. "Within a month, I have lost two close buddies of mine. I've watched you grow into an amazing young man that will never be forgotten. Cherish every moment you have with the people in your life. Rest in Peace Colby, I love you brotha."

Former Barron Collier wrestler Brenden Eddington died in an ATV accident last month, which also rocked the close-knit local wrestling community.

Former Palmetto Ridge quarterback Jacquez Carter also offered his condolences through an Instagram post.

"I fell to the floor in tears and shock and I still can't believe it," Carter wrote. "I don't know what to do with myself knowing I just lost a close friend of mine. State Champion Wrestler and was headed D1 in football, didn't get to say it but I love you Colby. This type of pain hit different, this next season is for you. Don't even feel real typing this right now. God's Angel."

Singletary won the Class 2A state championship at 182 pounds as a sophomore, and then again this year at 195 pounds to cap a sterling 53-1 season.

Although he was a highly decorated wrestler, football seemed to be his passion. A two-year starter at linebacker, Singletary had Division I offers from Southern Mississippi, Buffalo and Troy.

Singletary won the Naples Daily News Male Athlete of the Year at the Southwest Florida Sports Awards following his sophomore season and was again a nominee for the award this year.

Singletary came from a long line of outstanding wrestlers.

Older brothers Cody and Chase were also state wrestling champions – Cody at Palmetto Ridge and Chase a two-time New Jersey champion at Blair Academy after transferring there from Palmetto Ridge after his freshman season.

Chase is now a starter on the nationally-ranked Ohio State wrestling team. Father Casey was a state-runner up for Barron Collier in 1990.
