HOUSTON (AP) — Associated Press journalist Michael Graczyk, who witnessed more than 400 executions in Texas, will retire Tuesday after nearly 46 years with the news service.

The 68-year-old reporter may have observed more executions than any other person in the United States since the Supreme Court reinstated the death penalty in 1976. Millions of readers in Texas and beyond relied on his coverage in America's most active death penalty state.

He built a reputation for fairness with death row inmates, their families, their victims' families and their lawyers, as well as prison officials and advocates on both sides of capital punishment.

He made a point of visiting every inmate willing to be interviewed. Over time, he gained notoriety himself as an authority on the death penalty and a witness to history.
