DAYTONA BEACH, Fla. (WFLA) — The person of interest in the deaths of a married couple who had their throats cut over the weekend has been arrested, according to the Daytona Beach Police Department.

The man was identified as 32-year-old Jean Macean.

Officers found Brenda and Terry Aultman dead with their throats slashed near the side of the road Sunday morning. Investigators said the couple was riding their bikes when they were attacked.

It’s unclear how long their bodies had been on the road.

“They didn’t deserve what happened to them,” a family member identified as Sarah said. “This is a monster.”

Young said Macean has a minimal criminal history mostly relating to drugs. He has been arrested on one felony arrest in the past.

According to the Daytona Beach Police Chief Jakari Young, a motive has not yet been provided.

“This is probably one of the most vicious and gruesome incidents that I’ve witnessed in my 20 years,” Chief Young said. “We can’t rule out that this may be totally random, but if it is totally random, the person responsible has to be deranged.”

In a tweet, Young thanked U.S. Marshalls, Orlando police and the Orange County Sheriff’s Office for their help in locating Macean.

He has been charged with two counts of first-degree murder.
