A Louisiana man is behind bars after allegedly confessing to killing a couple he lived with.

Last Thursday, 54-year-old Iva and 55-year-old Lewis "Payton" Travis were reported missing to the Tangipahoa Parish Sheriff's Office. They had not been seen or heard from since Valentine's Day, WDSU, WBRZ and WGNO report.

During their investigation, authorities made contact with the couple's roommate, 34-year-old Kevin Buckley.

Buckley then allegedly confessed to killing the couple and revealed to detectives the location of their bodies.

Authorities believe a disagreement between Buckley and the couple led to the killings. The 34-year-old was taken into custody and charged with two counts of first-degree murder.

It is unclear how the couple died. The investigation remains ongoing. PEOPLE's calls to the Tangipahoa Parish Sheriff's Office Monday were not immediately returned.

Attorney information for Buckley was not available Monday, and it was not immediately clear if he had entered a plea.
