RESERVE, La. -- Two people are behind bars, charged with murdering a Reserve couple.
The bodies of Lakeitha and Kenneth Joseph were found in the Intercoastal Waterway weeks after their disappearance.
Now New Orleans Police say two people are responsible for their murders.
"It's very shocking to know they were weighed down, to just imagine what they went through," said Joshua Jones during an interview with Eyewitness News earlier this month.
Wednesday night, Jones said he was with Kenneth Joseph's family after hearing the arrests were made. The loved ones were unable to speak about the break in the case.
The NOPD is charging 25-year-old Brittany Martin and 37-year-old Horatio Johnson with two counts of second-degree murder. Police say both suspects are from St. John the Baptist Parish.
According to the NOPD, Martin and Johnson turned themselves over to the U.S. Marshal's Task Force. They were booked as fugitives at the St. John Parish Jail. The NOPD says they'll be transported to the Orleans Parish Prison and booked on murder charges.
On Feb. 19, the Reserve couple went missing from their home. Authorities say their van was later found in Atlanta, and then their bodies were found earlier this year.
According to a search warrant, surveillance video at a Walmart in Kenner shows a couple buying kettle bells, hooded sweatshirts, gripping gloves, fishing line and blue rope.
The warrant describes how blue rope was found around both victims feet, and in the case of Kenneth Joseph, investigators believe it was tied to a 30-pound kettle ball.
While two suspects sit behind bars facing murder charges, it's unclear why the young couple became the target of such a vicious crime.
"No enemies whatsoever, nicest person you could meet, help you out if you need help," said Joshua Jones, a long-time friend of the couple.
The NOPD has scheduled a news conference on Thursday afternoon to talk more about the case.
