Madden, 34, who went by Konyale Madden on Facebook, was found dead in her home on Hayden Lane in Savannah Estates by friends on Sunday, Sept. 1, Sgt. Larry Kish told the Denton Record-Chronicle. Savannah is a small town east of Denton.
Officials thought Madden had been dead since Friday night or Saturday morning and are investigating her death as a homicide.
Investigators said they initially believed the body to be a female, but did not elaborate on Madden’s identity.
Calls to Kish were not immediately returned.
Jermone Antonio Jones, a longtime friend of Madden’s, told the Denton Record-Chronicle that Madden identified as female growing up.
“As a child, he [Artegus] considered himself as a female and all through school,” Jones said. “He was the life of the party. If you had a party, you would want Artegus there.”
The two grew up together in Longview, where Madden attended high school.
The preliminary cause of death hasn’t been revealed by the Tarrant County Medical Examiner’s Office, which covers Denton County.
The investigation is still ongoing and no arrests have been made. People with information leading to the death should contact Sgt. Kish at 940-349-1665.
Madden’s funeral was Sept. 7 in Longview, according to her obituary. Her family requested donations be made in her name to MD Anderson Cancer Center in Houston in lieu of flowers.
