Attorneys for condemned man seek halt to today's execution

ST. LOUIS -- Attorneys for a condemned Missouri inmate warn the state is preparing to execute a potentially innocent man.

Marcellus Williams, 48, is scheduled to die today at the state prison in Bonne Terre for stabbing to death former St. Louis Post-Dispatch reporter Lisha Gayle during a 1998 robbery at her home in the suburb of University City.

It would be the state's second execution of 2017.

Williams' attorneys have appealed to the U.S. Supreme Court, seeking a new hearing or the commutation of his sentence to life in prison.

They also have asked Republican Gov. Eric Greitens for clemency.

A spokesman for Greitens didn't reply to a message seeking comment.

Attorney Kent Gipson contends DNA testing conducted in December using techniques that were not available at the time of the killing showed DNA found on the knife matches an unknown man, but not Williams.

He also cited previous DNA testing of hairs found from Gayle's shirt and fingernails that excluded Williams and said footprints at the scene did not match Williams.

The new evidence "means in our mind the actual killer is not him," Gipson said last week.

Loree Anne Paradise, a spokeswoman for Attorney General Josh Hawley, said the office remains confident Williams is guilty based on other evidence in the case.

Gipson said Williams' conviction was based on the testimony of two convicted felons who were out for a $10,000 reward. One was Williams' former girlfriend, and the other was his former cellmate.

Gayle, 42, was stabbed repeatedly Aug. 11, 1998, after surprising the burglar in her home. Gayle was a reporter at the Post-Dispatch from 1981 to 1992, leaving to do social work.

In addition to the murder conviction, Williams is also serving consecutive terms of life in prison for robbery and 30 years each for burglary and weapons crimes.

After several years of being among the states with the highest number of executions, the pace in Missouri has slowed.

The only execution in this state this year was in January, when Mark Christeson was put to death for killing a woman and her two children.
