Texas is scheduled to become the first state in the U.S. this year to execute a death row inmate.

Curtis Moore is scheduled to die Wednesday evening for the murders of three people during a pair of drug rip-off robberies in Fort Worth more than 13 years ago.

The 40-year-old inmate's first run-in with the criminal justice system came at age 12 as a runaway, and he kept getting into worse trouble, as he got older.

His rap sheet showed convictions for theft, robbery, and weapon and drug possession that earned him prison terms.

Moore is among six death row inmates scheduled to die in Huntsville over the next 15 days.

Two are set for execution next week.

Killed in the 1995 shootings were Roderick Moore, 24, LaTanya Boone, 21, and Darrel Hoyle, 21, all of Fort Worth.
