DELAND, Fla. – A coordinated investigation among multiple law enforcement agencies has led to the arrest of a Florida man in connection with the July homicide of an Arkansas woman.
On Wednesday, October 1, 2025, at approximately 3 p.m., the Volusia County Sheriff’s Office in DeLand, Fla., arrested Mark R. Brown, 68, of DeLand, Fla. on charges of Capital Murder in the death of his sister, Mona Sloop, 69, of Leslie, Ark.
Sloop was found deceased at her residence on Shady Grove Road in Searcy County on July 22, 2025.
The arrest followed a joint investigation conducted by the Arkansas State Police (ASP) Criminal Investigation Division (CID), the Searcy County Sheriff’s Office (SCSO), and the 20th Judicial District Drug Crimes Task Force. At the request of the SCSO, ASP Special Agents assisted in the investigation and traveled to Florida with SCSO investigators to collect evidence that ultimately led to Brown’s arrest.
Brown was booked into the Volusia County Detention Center, where he awaits extradition.
The investigation is on-going and additional arrests are possible.
