April 15 (UPI) -- Authorities in northern Florida arrested KaShawn Nicola Roper on Wednesday, a day after the fugitive was added to the FBI's Ten Most Wanted list over an alleged 2020 fatal shooting in Missouri.

Federal and local police have been hunting the 50-year-old woman since Aug. 23, 2020, when authorities allege she opened fire on an occupied car in Kansas City, Mo., killing 23-year-old mother Jazmyn Henrion and injuring a second person.

Roper was charged by the Jackson County Prosecutor's Office that September with a slew of offenses, including second-degree murder. A federal arrest warrant was issued for Roper on July 1, 2021, after authorities said they believed she had fled the state immediately following the shooting.

On Tuesday, the FBI added her to its Ten Most Wanted Fugitives list, offering up to a $1 million reward leading to her arrest and conviction.

Police officers in High Springs, Fla., located about 75 miles southwest of Jacksonville, arrested Roper on Wednesday morning during a traffic stop.
