Four members of an Orlando family on a beach vacation were killed early Sunday morning when a drunken driver ran a red light and slammed into their car in St. Petersburg, police said.

Elroy "Roy" McConnell, 51, an accountant and triathlete, was at the wheel of a Ford Fusion about 12:45 a.m. when a speeding southbound Chevrolet Impala ran the light on Dr. Martin Luther King Street North at 22nd Avenue North, St. Petersburg police said.

McConnell, 51, and his sons, Elroy "Roy" McConnell III, 28, of Pineville, La.; Nathan McConnell, 24, of Orlando; and Kelly McConnell, 19, of Orlando were pronounced dead at the scene. The collision propelled their car into a large support beam for a sign.

The driver of the Impala, Demetrius D. Jordan, 20, was arrested on four counts of DUI manslaughter, along with DUI causing serious bodily injury and possession of alcohol by a minor. Jordan and a passenger in his car, Mario D. Robinson, 20, were taken to Bayfront Medical Center in St. Petersburg with serious injuries.

"It's just too much to bear," said Tonya Bachand of Orlando, a friend of the family for 25 years.

The men had gone to the movies for a guys' night out and were headed back to the rented house where they and their families had been staying in Redington Beach, friends and family said.

"This is the best idea we have had in years ... rented a house on the beach for Amy, Kelly and I and my two older son's families," Roy McConnell wrote on his Facebook page. "Paid less than one nice hotel room and this place is really well put together."

According to Bachand, McConnell "was an amazing, amazing man - very Christian. They called him Iron Man because of the triathlons he won."

All three McConnell boys graduated from University High School near the University of Central Florida and were Christian athletes who played football, said their aunt, Cheryl McConnell.

Roy III was married and had a 4-month-old son, Elroy McConnell IV. He worked for JCPenney.

Nathan McConnell, an electrician, was married with a 2-year-old daughter. His brother Kelly had just finished his freshman year at the University of Miami, where he played rugby, according to his Facebook page.

"I really love my large family and close immediate family," Kelly McConnell wrote on Facebook, also praising his girlfriend of more than a year as "pretty awesome." "They're all really great and unconditionally supportive. I have some of the best friends I could ask for."

His father, originally from Pennsylvania, was chief executive of iCFO, an Orlando financial-consulting firm. He founded the University Cougars, a local Pop Warner league. He was active at University Carillon United Methodist Church in Oviedo, where he played the drums in the praise band and served on the church's finance committee.

"I like just about anything and everything," Roy McConnell wrote in another Facebook comment. "I have a great wife and 3 sons, only one left at home. I have been blessed in so many ways. I love the adventure of faith, family, work, and the various forms of play."

As the recession bore down on many of his fellow church members, Roy McConnell helped them with their finances, said Pastor Joe MacLaren

"People would come to me and be beside themselves," said MacLaren, referred them to McConnell. "He'd take all their bank statements and he'd give them the best advice he could. And he never charged anyone. He did it all out of the goodness of his heart."

MacLaren said that, though McConnell was a believer in recent years, he started as a skeptic.

"He was not a Christian when he started coming to church," said MacLaren. "He sat in the back and he folded his arms. Yet he ended up being one of our most passionate people in the church, about ministry and Jesus."

McConnell also ran the local chapter of the Fellowship of Christian Athletes' Endurance program, an adult ministry that reaches out to triathletes, marathon runners and cyclists.

"Even if his life was snuffed out early, he made a lasting legacy by the people he touched," said Del Wright, regional director of the Fellowship of Christian Athletes.

Funeral arrangements had not been made late Sunday.
