An Oklahoma man convicted in the murder of two people in Oklahoma City more than 20 years ago has been executed, marking the first death by capital punishment in the state this year.

Michael Dewayne Smith, 41, received a lethal injection at the Oklahoma State Penitentiary on Thursday morning and was pronounced dead at 10:20 am, according to a spokesperson from the Oklahoma Department of Corrections.

Smith declined to request a final meal. Chief of Public Relations Kay Thompson told DailyMail.com that the inmate was provided canteen items and that he was a vegetarian.

The 41-year-old was convicted in the separate shooting deaths of Janet Moore, 41, and Sharath Pulluru, 22, in February 2002.
