On the afternoon of Thursday, May 12, 1994, Bert Allen Mann was found with fatal stab wounds in the kitchen floor of his residence, located in the 2500 block of Star Grass Circle. Evidence at the scene suggested the suspect forced entry into the home through a rear sliding glass door and was discovered by Mann when he returned home from work. The suspect and Mann fought near the front door, but Mann was ultimately stabbed to death by the suspect. During the struggle, the suspect was injured and bled inside the home. An exhaustive investigation over the next several years produced over forty persons of interest.
In 2005, a blood stain from the scene was tested for DNA. The profile obtained from this stain was determined to be from an unidentified male. 
The DNA profile was entered into Combined DNA Index System (CODIS), but no match was found. In March of 2023, the unknown profile was sent to Bode Technology for Forensic Genetic Genealogy. In June 2023, Bode Technology identified a possible suspect who was unknown to the investigation.
Over the last 29 years, over 20 detectives have contributed to the progression and investigation of this case. There were multiple non-sworn employees that also contributed to the conclusion to include crime scene units, latent print examiners and DNA Case Management employees. Bert Allen Mann is survived by his widow and his sister.
