Arrest warrant reveals suspects in Reserve couple's killings met in jail

RESERVE, LA (WVUE) - Two suspects arrested in connection with the deaths of a Reserve couple were in a romantic relationship that started in jail.

Court documents now reveal how Brittany Martin, 25, and Horatio Johnson, 37, met, and why their relationship caused Martin to be fired from her job as a corrections officer.

"They deserve justice and the people who did this need to be in jail for the rest of their lives," said St. John the Baptist Sheriff Mike Tregre.

Martin and Johnson each face two counts of second-degree murder in the deaths of Kenneth and Lakeitha Joseph. Their arrest warrants reveal that they met while Martin was employed as a corrections officer at the facility where Johnson was serving time for manslaughter in connection with a drug-related killing in Laplace in the 1990s. The warrant also states that Johnson is Kenneth Joseph's cousins.

According to the warrant, "(Martin) would later resign under investigation for engaging in an improper relationship with Horatio Johnson while he was an inmate at the facility."

Johnson was released from that prison in December 2013. The Josephs disappeared from their home on Feb. 18 of this year.

"At 1 a.m. on Feb. 19, Brittany Martin and Horatio Johnson were observed purchasing murder weapons on surveillance video, and Martin's credit card verified these purchases," said New Orleans Police Chief Ronal Serpas.

In March the Josephs' bodies were found in the Intracoastal Waterway.

Both has been bound by their feet with blue nylon rope and tied to a 30-pound kettle bell to weigh the bodies down.

The coroner's office determined both died of drowning.

According to the warrant, the NOPD's lead investigator interviewed another person, who is identified in the document only as "Witness 1." Witness 1 told police that he and another person, identified as "Blue," received the Josephs' van from Johnson, who asked them to clean it out and get rid of it.

The warrant states: "He and Blue then drove the van to Frank Mike Jr.'s residence, where they parked it. Witness 1stated that Horatio Johnson and his girlfriend Brittany Martin followed them."

"The van was delivered to Atlanta and then abandoned," Serpas said. "A forensic examination revealed that the blood in the van was a mixture of both victims."

Mike Jr. is in federal custody, accused of transporting the stolen vehicle across state lines.

Police said their intense investigation is far from over, indicating more arrests could follow.

Johnson is being held on a $1 million bond. Martin jailed on an $800,000 bond.
