Authorities in Florida have arrested the man they say stabbed a couple to death while they were bicycling back home.

Federal marshals, the Orange County Sheriff’s Office and the Orlando Police helped the Daytona Beach Police detain Jean Robert Macean, 32.

The Orlando man was arrested on Thursday, and was  charged with two counts of first-degree murder in connection with the killing of Terry and Brenda Aultman.

The Daytona Beach couple’s bodies were found early Sunday morning along the side of a road. At the time of the fatal attack, the husband, 48, and wife, 55, had been biking home after attending festivities at Daytona Beach’s annual Bike Week.

Daytona Beach Police Chief Jakari Young said the murders were “one of the most brutal” he has seen in his 20-plus career.

“We want to thank the entire Daytona Beach community and the communities around us for providing our detectives with over 100 tips,” Young said in a statement. “We appreciate that level of cooperation in such a serious matter.”

The arrest comes days after police released surveillance footage of the man they said was a chief suspect in the killings.
