The FBI is offering up to a $50,000 reward for a teenager who remains wanted in the killings of three teens at a Texas convenience store in 2021. The reward is for any tips that lead to 18-year-old Abel Elias Acosta's arrest and conviction, the FBI's Dallas Field Office said in a Thursday, April 9, news release shared to Facebook. "Acosta is wanted in Dallas County, where he faces charges including capital murder of multiple persons, in connection with the fatal shooting of three teenagers in Garland, Texas in December 2021," the agency said.
