The Associated Press reports this morning that a man has been arrested in the death of Marlon Alfaro, the 23-year-old from Irving who was beaten and run over in a Lower Greenville Avenue club's parking lot on January 25. Dallas police and a certain Barking Dog had speculated in a KXAS-Channel 5 story that Alfaro's murder, which took place after an argument turned into an altercation, was gang-related. Which makes 23-year-old Frank Farias an unlikely suspect: Since August 2006, he's been a member of the 377th Medical Support Squadron out of Kirtland Air Force Base in Albuquerque, New Mexico, where he's being held till he's extradited to Dallas to face first-degree murder charges following his arrest on Friday.
