Robert Miquel Johnson, age 31, has been charged with murder over a month after allegedly strangling his girlfriend to death and attempting to sell off a vehicle with her body in the back seat.

This comes over a month after the body of 44-year-old Pamela Paz was found the morning in a small parking area on Pennington Bend Road at the Briley Parkway overpass.

Paz was last seen alive by family at her grandmother’s home in the town of Smyrna, Tennessee, days earlier and that Paz was spending time with an ex-boyfriend. An autopsy later showed Paz died from neck trauma and/or strangulation.

Johnson was identified as a suspect during the course of an investigation. Detectives later located a witness who reported that the day before Paz’s body was found, Police said Johnson attempted to sell her a Dodge Charger “with the victim deceased in the back seat.”

Johnson was already jailed in Wilson County on unrelated charges. He was to be booked in Nashville for criminal homicide.
