BAXTER COUNTY, AR (KAIT) - Three suspects in a Baxter County arson and death investigation are now facing two counts of capital murder.
Mikayla Jordan Mynk, 20; Zack Tyler Grayham, 23; and Nicholas Ian Roos, 24, were arrested Nov. 16 in connection with the deaths of a Midway couple.
Baxter County Sheriff John Montgomery said in a press release that remains found from the house fire at 447 County Road 508 have been positively identified by the Arkansas State Medical Examiner's Office as that of 71-year-old Ladonna Rice.
That identification was made Tuesday through DNA analysis.
Sheriff Montgomery said deputies arrested the three after receiving a tip about their possible involvement.
Investigators believe the suspects went to the Rices' home on Saturday, Nov. 7, and killed the couple before stealing various items, including a large screen TV and the couple's 2015 GMC Sierra Denali.
Deputies found the torched truck on Sunday, near Bruce Creek.
Investigators found human remains in the debris of the burned house. The search continued and more remains were found the following day.
The remains were sent to the Arkansas State Medical Examiner's Office in Little Rock where one set was positively identified as belonging to 75-year-old Donald Rice.
DNA evidence was collected from Ladonna Rice's relatives to positively identify the other remains.
After the deaths were publicized, Sheriff John Montgomery said several citizens came forward offering dozens of tips and information about the case.
One of those tips led investigators to look for Roos and Mynk. Deputies arrested the pair during a traffic stop on Wednesday, Nov. 11, the sheriff said.
The two were taken to the Baxter County Detention Center on charges related to a separate residential burglary on County Road 7 and a commercial burglary at Dean's Top and Canvas near Mountain Home, according to Montgomery.
After obtaining a search warrant, investigators reported finding items belonging to the Rices, as well as items stolen from the other two burglaries, in Mynk's home on CR 709.
Investigators picked up Grayham on Friday.
Prosecuting Attorney David Ethredge said evidence indicated all three suspects were involved in the deaths of Donald and Ladonna Rice to varying degrees, according to Montgomery.
Although arrests have been made, the sheriff said the investigation is far from over and urges anyone with information—"no matter how small or trivial"—to contact his office.
All three suspects are charged with two counts of capital murder, arson, aggravated robbery and other offenses.
They are currently being held in the Baxter County Detention Center.
