EDINBURG, TEXAS (AP) -- A judge is expected to decide whether a South Texas 17-year-old charged with attempted murder in a federal agent's shooting will stand trial as an adult.

State District Judge Jesse Contreras said he would announce his decision Tuesday in Edinburg regarding the teen, who was 16 when the shooting occurred.

Hidalgo County prosecutors have argued that the boy should face the charge as an adult because of the seriousness of the crime. The defense says it was a mistake made by a boy.

Special Agent Kelton Harrison of U.S. Immigration and Customs Enforcement was shot before dawn July 3 in Hargill, a rural community northeast of Edinburg.

Officials say the teen, an older brother and his father pursued and shot Harrison while he was conducting surveillance in the area.
