A Forestville man was convicted Thursday of murdering the mother of his daughter after the woman had sought child support from him, officials said.

Fabian Andre Shim, 47, was found guilty of first-degree murder in the 2006 shooting death of 26-year-old Reina Natasha Lynch. He is scheduled to be sentenced on June 25 and could receive life in prison without the possibility of parole.

In November 2006, Lynch was found fatally shot inside a locked guard station at the Federal Express mailing facility in Beltsville. Lynch was a guard at the facility and was working the overnight shift, prosecutors said.

Lynch and Shim were parents of a 7-year-old girl, and Lynch had initiated child-support proceedings against Shim earlier that year, prosecutors said. They had attended a mediation hearing concerning the child support during the month of the slaying.

A few days after Lynch was killed, Shim's then-fiancee called 911 and said that Shim confessed to the killing, prosecutors said. She also told police that about a car that had been in Shim's possession that was later found to contain the murder weapon.

Marlyn Evans, Lynch's mother, said she was pleased with the verdict.

"Oh my God, so much satisfaction. We are so relieved," Evans said.

Shim had been convicted in the case in 2007, but the Maryland Court of Appeals overturned the conviction because of an issue relating to jury selection.
