A Webb County, Texas grand jury has indicted a man nearly a decade after he allegedly attempted to sexually assault the mother of nine children and killed her as she was walking home from work.

Using advanced forensic methods, investigators with the Texas Rangers and Laredo Police Department identified 42-year-old Sergio Mendez as the culprit who allegedly killed 33-year-old Janette Escamilla Jaramillo of Laredo, Texas, in 2016.

The Texas Rangers said in a press release that on May 18, 2016, Jaramillo left work to go home at about midnight, though she never made it to her destination.

Jaramillo’s body was discovered under a skate ramp just after daybreak at Seven Flags Park, by employees of the Laredo Parks and Recreation Department.

The funding allows agencies across the U.S. to further investigate unsolved sexual assaults and sexually-related homicides.

Investigators used the funds to conduct advanced DNA testing, which ultimately identified Mendez as a suspect.

On March 12, a grand jury indicted Mendez. He is currently in custody and serving a 10-year prison sentence in Edinburg, Texas, for an unrelated crime.
