Demarco Marquie Jones, 29 of Farmington, was charged* today with one count of second-degree intentional murder in connection with the death of 26-year-old Tatianna Marie Ehnes-Giles, announced Dakota County Attorney Kathy Keena.
According to the criminal complaint, at approximately 2:23 p.m. on Wednesday, Dec. 24, deputies from the Dakota County Sheriff's Office were called to a residence in Castle Rock Township. The reporting party, the victim's mother, told dispatch that Ehnes-Giles was shot in the head by Jones, the victim's boyfriend. She stated her daughter was not breathing.
After deputies arrived, Jones was located at the top of the stairs on the second floor of the residence. He had blood on his hands and on the back of his head. Jones was verbally responsive and told the deputies the gun was “in the room." He was then transported to a hospital for medical care.
Ehnes-Giles was found in her bedroom, lying on the bed with visible injuries to her head. Medics arrived and confirmed that she was deceased. A handgun and two spent shell casings were found in the bedroom.
Deputies were told that Ehnes-Giles and Jones lived upstairs in the residence with their two children, while the victim's mother and brother lived in the lower area of the home.
An autopsy was performed by the Hennepin County Medical Examiner's Office and determined that Ehnes-Giles died as a result of a single gunshot wound to the head and the manner of death was homicide.
Jones is currently in custody at the hospital where he continues to receive medical treatment. Bail was set at $2 million with conditions by Judge Dannia Edwards. Jones will be transferred to the Dakota County Jail after he is medically cleared.
His next court hearing is scheduled for Jan. 5, 2026, at 9 a.m. in Hastings.
County Attorney Keena thanked the Dakota County Sheriff's Office for their response and work on this case.
