Two more suspects have been arrested in the murders of a Reserve couple.
Brittany Martin, 25, and Horatio Johnson, 37, turned themselves in Wednesday to the U. S. Marshals Task Force and members of the St. John Parish Sheriff's Office after learning that there were warrants for their arrests in connection with the deaths of Lakeitha and Kenneth Joseph.
Both were booked into the St. John Parish Sheriff's Jail as fugitives.
When transferred to Orleans Parish, they will each be booked with two counts of second-degree murder.
Another suspect, Frank Mike Jr., was arrested April 29. He is accused of driving the Joseph's stolen van across state lines.
The investigation has taken several twists and turns over the past months. The Josephs disappeared Feb. 19, and their Reserve home was found unlocked and ransacked. A minivan they had borrowed from a relative was gone, but was found days later in Atlanta.
The couple's bodies were found floating in the Intracoastal Waterway in March. Autopsies originally showed the couple died of drowning.
In early April, Coroner Dr. Frank Minyard classified the deaths as homicides. Court documents show the feet of both Kenneth and Lakeitha were bound with a blue nylon rope. The rope on Kenneth was tethered to the handle of a 30 pound kettlebell in an apparent effort to weigh down his remains.
A search warrant showed that police obtained blood evidence from inside the recovered van. The search warrant also revealed that police had checked a Walmart in Kenner, where surveillance video shows a man and woman buying two kettlebells and other items on Feb. 19, the morning the couple disappeared.
New Orleans police said more information will be released at a news conference Thursday.
