There were no leads and the investigation was placed in the cold cases file, abandoned for decades. However, in early 2019, a woman in her 50s informed the police that as an 11-year-old girl, she had seen her mother's companion dismember and bury a body. The police used dogs to scour the property where she had lived at the time, and found human remains, but were unable to identify the victim. Only the pelvis and part of the torso were found. Identification of victim 
Using material from the remains, investigators generated a genetic profile. Two years later, still unable to identify Steitz as the victim, the FBI were called upon, as well as an external forensic genealogy laboratory, Othram Detectives were then able to find close relatives and identified Seitz through DNA samples.

He and his brother had owned the barbershop, where Seitz visited when he disappeared, located only a few city blocks from Seitz' home He was arrested, arraigned, and indicted by a grand jury in November 2021.
