Texas executes John Balentine, sixth inmate to be put to death in US this year

Balentine, 54, was convicted of triple murder in what attorneys argued was a trial marred by racial bias

A man convicted of killing three teenagers while they slept in a Texas home more than 25 years ago was executed on Wednesday, the sixth inmate to be put to death in the US this year and the second in as many days.

John Balentine, 54, whose attorneys argued his trial was marred by racial bias, received a lethal injection at the state penitentiary in Huntsville, for the January 1998 deaths of Edward Mark Caylor, 17, Kai Brooke Geyer, 15, and Steven Watson, 15, in Amarillo. Prosecutors said all three were shot once in the head.
