San Antonio Capital Murder Suspect Arrested by U.S. Marshals

Del Rio, TX – Members of the U.S. Marshals Lone Star Fugitive Task Force and officials with Customs and Border Protection, arrested a Bexar County capital murder suspect in Eagle Pass on March 4th. Isaac Estrada, 26, is accused of brutally stabbing Courtney Phillipson on April 5, 2015. Phillipson, a single mother, was survived by her young child.

Shortly after the murder, U.S. Marshals assigned to the Lone Star Fugitive Task Force began working with the San Antonio Police Department to locate Estrada.

In October of 2015, U.S. Marshals elevated the Estrada investigation to major cases status. The story was broadcast nationwide, most prominently by John Walsh on his “In Pursuit” series. Rewards were offered and numerous leads were generated, but Estrada avoided capture for nearly eight years.

Susan Pamerleau, U.S. Marshal for the Western District of Texas, recalls the diligent efforts of San Antonio Police Department investigators, and the teamwork displayed between local and federal agencies.

“Violent criminals’ prey on the innocent, ending lives and shattering the neighborhoods around them,” she said. “From the Police Officers who responded to the initial call, to the Deputy U.S. Marshals who tracked Estrada down and arrested him, each professional within our team is dedicated to ending violence and putting criminals behind bars. This case shows that no matter how far you run, you will be found, you will be arrested, and our communities will be more safe.”

The Lone Star Fugitive Task Force is comprised of numerous local, state, federal partners across west Texas, and includes the Bexar County Sheriff’s Office; New Braunfels Police Department; Jourdanton Police Department; Texas Department of Public Safety; Texas Attorney General’s Office; Texas Department of Criminal Justice – Office of the Inspector General; Bureau of Alcohol, Tobacco, Firearms and Explosives; Naval Criminal Investigative Service; U.S. Immigration and Customs Enforcement; U.S. Customs and Border Protection; Bureau of Alcohol, Tobacco, Firearms and Explosives; the Drug Enforcement Agency, the U.S. Attorney’s Office and the U.S. Marshals Service.
