TORRANCE, Calif.–A 52-year-old man was sentenced today to 25 years to life in prison for the 1994 strangulation murder of his wife of eight months, a CIA employee whose body was found in the trunk of her car near LAX.

Andre Jackson was convicted in April of first-degree murder for the slaying of Marie Singleton-Jackson, 33.

Singleton-Jackson, a CIA communications specialist, was last seen alive on Nov. 11, 1994, according to the Los Angeles County District Attorney’s Office. Her body was discovered five days later in the trunk of her vehicle, which was parked on Vista Del Mar north of Imperial Highway near Dockweiler State Beach.

The Inglewood Police Department began a homicide investigation in 1994, with Jackson identified as the prime suspect. The FBI also began an investigation based on concerns that her slaying could have been linked to her CIA status.

The FBI eventually concluded her death was not connected to her work, and the investigation went cold until it was re-opened in 2003.

Jackson was arrested in Tempe, Ariz., in 2008 by the FBI’S Fugitive Task Force. Investigators determined that he strangled his wife in their garage on Hazel Street and then put her body in the trunk of her Saab.
