The Sequatchie County Sheriff's Department has made another arrest in a meth lab explosion that caused a fire in a mobile home in Dunlap Friday night.

Authorities tell us Juanita Gray faces charges of manufacturing meth, and initiation of a process to manufacture meth. We're told she is the person who rented the trailer that was the scene of the explosion.

While Gray is in jail, we're learning more about the other two involved.

Police arrested one woman, 20-year-old Cynthia Morgan, Friday night. Deputies tell us Morgan and Stanley Stewart were boyfriend and girlfriend, and both have prior charges relating to methamphetamine.

Stewart, who remains at Vanderbilt Medical Center for burns suffered in the explosion, has been to prison before on charges of manufacturing meth, according to the Sheriff's Department.

They also say Mogan has been arrested several times where meth labs had been found.

Gray has a previous arrest for violating the pseudophedrine law.
