Police made another arrest Sunday in the disappearance and death of a missing reserve police officer from a small town in Virginia.

Anthony L. White, 22, of Mineral, Va., was taken into custody without incident in Louisa County and charged with one felony count of gang participation, according to Virginia State Police.

He is the sixth suspect charged in the case of Kevin Wayne Quick, 45, of Rockfish, Va., who went missing a week ago and whose remains were found Thursday in a remote area in Goochland County, about halfway between Richmond and Charlottesville. Police confirmed that the remains were Quick’s late Friday evening, but have not yet released the cause of death.

On Friday, police charged three others with a felony count of gang participation and what police called a charge of “principle in second degree to the crime of murder.”

“This means these individuals are not being charged with Quick’s homicide but in association with his death,” Virginia State Police said in a statement.

The three were arrested Thursday night outside a hotel in Prince William County. Authorities identified them as 22-year-old Gert Wright of Danville, also known as Halisi Uhuru; 49-year-old Leslie Hope Casterlow of Manassas; and 31-year-old Anthony D. Stokes Jr. of Manassas.

On Tuesday night, police arrested two other suspects — siblings from Albemarle County — at an Alexandria hotel. Mersadies Shelton, 20, and Daniel Mathis, 18, were charged with grand larceny for the theft of Quick’s silver 1999 Toyota 4Runner.

Police found the abandoned SUV last Monday at a residence in Mineral, Va.

“We’re still piecing together this network of individuals,” said Corinne Geller, a spokesman for the Virginia State Police.

Quick was last seen on Jan. 31, leaving his mother’s house in Afton around 10:15 p.m. He was expected to visit his girlfriend about 20 miles away. But he never made it. He was reported missing the next day.

Quick was a 24-year member of the Waynesboro Police Department’s reserve police force, according to the Associated Press. Sgt. Brian Edwards, a spokesman for the department, has said Quick had recently been laid off from his job as a production supervisor and was working as a painter, AP reported.

Waynesboro, pop. 21,000, is in the Shenandoah Valley, about 20 miles west of Charlottesville.
