Detectives don't believe this was a random shooting.
They say a 21-year-old Mississippi man targeted the Jefferson County couple for a specific reason...money.
Early Friday morning, a family member found the bodies of 62-year-old Anthony Branch and 58-year-old Deborah Moncrief.
Today, authorities found their suspect.
21-year-old William Childress is charged with two counts of capital murder.
Major Lafayette Woods says interviews with family, friends and neighbors led to the arrest.
The murders happened down a private drive out in the county.
It's a tight-knit community with only about six homes.
Everybody knows everybody, but no one wanted to talk to us today about the arrest including the family members who gathered at their loved ones home.
Meanwhile, sheriff's deputies picked up Childress in another county.
After questioning him, detectives say he led them right to the murder weapon.
Major Woods said, "In this case he was very forthcoming."
Major Woods says Childress is engaged to Deborah Moncrief's niece and that's how he knew the couple.
Detectives say money was Childress's motive in the shootings, but they're not saying much more about it.
Major Woods said, "That's part of the investigation itself. We can't speak to the fact if it was given or he took it."
Childress is behind bars with no bond.
He's expected to be in court on Monday.
Right now, investigators believe he was the only one involved in this crime.
If convicted, Childress could face the death penalty.
