HOUSTON -- A death row inmate who slipped out of the Harris County courthouse wearing street clothes has been captured in Shreveport, La., the U.S. Marshals Service said Sunday night.

Marianne Matus, a Marshals spokeswoman in Houston, confirmed convicted killer Charles Victor Thompson was in custody. No other details were immediately available.

Thompson, 35, fled the Harris County Jail late Thursday, using a smuggled set of clothes and a fake identification badge to get past the guards.

Harris County Sheriff's Department spokesman Lt. John Martin said Friday that Thompson's escape resulted from "multiple errors" by jail personnel.

Thompson was convicted in 1999 for the shooting deaths a year earlier of his ex-girlfriend, Dennise Hayslip, 39, of Tomball, and her new boyfriend, Darren Keith Cain, 30, of nearby Spring.

Matus had said earlier Sunday that authorities had received valuable tips about Thompson's possible whereabouts.
