DETROIT - Police say they are pursuing a murder charge against the husband of Alicia Fox, a slain Detroit woman whose two children remain missing.
Detroit Police Chief James Craig said Thursday that Erin Justice, 28, was taken into custody in Atlanta. Craig says he's hopeful the children are alive and believes Justice has information on their whereabouts.
CBS Detroit reports a second suspect - a 27-year-old man, who police believe was an accessory to the murder, is also in custody. He was reportedly arrested in Detroit.
Fox's decomposed body, shot twice in the head, was discovered Monday night in a vacant Detroit house. Authorities are searching for her children, 6-year-old Kaylah Hunter and 8-month-old Kristian Justice.
Craig reportedly confirmed that blood evidence was collected at Fox's home. He said it is not yet clear whether it is connected to a victim or victims in the case.
Officers searched around Fox's home Wednesday night using shovels after police received a tip that the children might have been buried in the backyard, according to the station.
The Wayne County prosecutor's office says the warrant for a murder charge against Justice is being reviewed.
Anyone with information on the children's whereabouts is asked to call Detroit Police or Crime Stoppers at 1-800-SPEAK-UP.
