During the investigation, authorities discovered that Birgfeld worked as an escort for Models Inc. under the name Carrie, presumably to support her family.
When Birgfeld’s client list was discovered, authorities went through it to narrow down the suspect list, and they came across a married man named Lester Ralph Jones.
Jones initially denied knowing Birgfeld, but later revealed that she had given him a naked massage. Jones worked as a mechanic across the parking lot from where Birgfeld’s car was discovered.
One of the last calls she received was apparently from a burner phone. Jones was also seen buying one on surveillance video.
