A Texas man convicted of beating and suffocating a Dallas area pastor in his church during a robbery was put to death Wednesday evening, the second execution in the U.S. this year and the first of four scheduled in Texas over the next three months.

The Rev. Clint Dobson had a dream for his Texas church: to fill it with young families and children and spread the gospel that had changed the course of his own life at the age of 8. But Dobson never really got that chance.
