Kevin Johnson murdered a police officer

 Man who murdered police officer in 2005 has been executed in Missouri

Kevin Johnson -- who murdered a Kirkwood, Missouri, police officer in 2005 but claimed racial bias in his prosecution -- was executed Tuesday night by lethal injection.

Johnson, 37, was pronounced dead at 7:40 p.m. CT. He didn't give a final statement, according to Missouri Department of Corrections spokesperson Karen Pojmann.

On Monday, the Missouri Supreme Court had denied Johnson's request for a stay after hearing arguments that racial discrimination played a role in his prosecution.

Mary McEntee, the widow of Kirkwood Police Sgt. William McEntee, said her husband was killed on his hands and knees in front of people he dedicated his life to serve.

"When he left for work that day, we could not imagine that he would be executed by someone he gave his life to protect," she said at a media briefing Tuesday evening. "Bill didn't get to fight for his life. He didn't have the chance to be heard before a jury, to decide whether he would live or die."

She also thanked the prosecutors who put in the "hard work and endless hours ... for justice for Bill." 

The execution was not witnessed by Johnson's 19-year-old daughter, who had failed this month to get a federal court to prevent the state from executing her father unless she was permitted to be a witness.

Missouri law bars people younger than 21 from witnessing the proceeding.

Pojmann said Johnson met with his daughter earlier Tuesday.

Arguments by Johnson and special prosecutor rejected

On Monday, the Missouri Supreme Court heard arguments in two requests for a stay: one by Johnson, who was Black, and the other by a special prosecutor appointed at the request of the St. Louis County Prosecuting Attorney's Office, which secured Johnson's conviction on a first-degree murder charge and death sentence for the murder of McEntee.

Both requests sought a stay so claims of racial prejudice could be heard by the St. Louis County Circuit Court, which previously denied a motion by the special prosecutor to vacate Johnson's conviction, saying there was not enough time before Johnson's scheduled execution to hold a hearing.

"There simply is nothing here that Johnson has not raised (and that this Court has not rejected) before and, even if there were, Johnson offers no basis for raising any new or re-packaged versions of these oft-rejected claims at this late date," the Monday ruling said.

Gov. Mike Parson, a Republican, also on Monday denied a request for clemency from Johnson's attorneys.

"Mr. Johnson has received every protection afforded by the Missouri and United States Constitutions, and Mr. Johnson's conviction and sentence remain for his horrendous and callous crime," Parson said in a statement. "The State of Missouri will carry out Mr. Johnson's sentence according to the Court's order and deliver justice."

A defense attorney for Johnson decried Monday's state Supreme Court ruling as a "complete disregard for the law in this case."

"The Prosecutor in this case had requested that the Court stop the execution based on the compelling evidence he uncovered this past month establishing that Mr. Johnson was sentenced to death because he is Black," lawyer Shawn Nolan said in a statement. "The Missouri Supreme Court unconscionably refused to simply pause Mr. Johnson's execution date so that the Prosecutor could present this evidence to the lower court, who refused to consider it in the first instance given the press of time."

Claims of racial bias probed

Meantime, attorneys for Johnson argued in court records that racial discrimination played a role in his prosecution, pointing in their motion for a stay to "long-standing and pervasive racial bias" in St. Louis County prosecutors' "handling of this case and other death-eligible prosecutions, including the office's decisions of which offense to charge, which penalty to seek, and which jurors to strike."

The Missouri Attorney General's Office argued against a stay, saying the claims were without merit. The special prosecutor's "unproven claims," the AG's office said in a brief, do not amount to a concession of wrongdoing by the state, which stands by the conviction.

"The McEntee family has waited long enough for justice," the brief said, "and every day longer that they must wait is a day they are denied the chance to finally make peace with their loss."

Bob McCulloch, the longtime St. Louis prosecuting attorney who was voted out of office in 2018 after 27 years, has denied he treated Black and White defendants differently.

"Show me a similar case where the victim was Black and I didn't ask for death," he was quoted as saying by St. Louis Public Radio earlier this month about his time in office. "And then we have something to talk about. But that case just doesn't exist."

Officer was responding to fireworks call

Johnson was sentenced to die for the July 5, 2005, murder of McEntee, 43, who was called to Johnson's neighborhood in response to a report of fireworks.
