Wisconsin Sen. Kelda Roys recently voiced her support for abolishing the death penalty following the execution of a Missouri man who was sentenced to death for killing a police officer when he was 19 years old.

According to CNN, Kevin Johnson, a Missouri man, was executed on Tuesday by lethal injection for the killing of a police officer in 2005. Johnson, 37, had requested a stay of execution but was denied by the U.S. Supreme Court.

Johnson had been in prison since his daughter, Khorry Ramey, was 2 years old. In the days before his execution, Johnson requested that his now 19-year-old daughter be allowed to attend, but a judge ruled that her age prohibits her from attending, BBC reported.

"The terrible irony of Missouri arguing that a 19-year-old is mature enough to be killed by the state for his actions, but his now 19-year-old daughter is not mature enough to watch the state kill him. Abolish the death penalty," Roys wrote in a Nov. 28 Twitter post.

CNN reports that Johnson was given the death penalty for the July 5, 2005 murder of Kirkwood Police Sgt. William McEntee, 43, who was answering a call of fireworks being shot in Johnson's neighborhood. Earlier that same day, McEntee along with other officers had appeared at Johnson's home to serve a warrant for a probation violation. While the police were present at the residence, Johnson’s 12-year-old brother had a seizure and died. Johnson allegedly blamed the officers for his brother's death and shot McEntee when he returned to the neighborhood later in the day.

Johnson reportedly had no final words at his execution.
