Cortez Hamilton was
indicted in 2015 for the murder of his 35-year-old wife, Keisha Hamilton, and pleaded guilty to second-degree murder on Jan. 19. As part of the plea deal, Hamilton agreed to help state police locate her body.
Forensic investigators are still working to determine the identity of the remains, which were found close to the family's home south of Smyrna, Delaware, according to the state Justice Department.
Authorities say that Hamilton killed his wife in January 2015 and then fled to Indiana with their two young children, where he was taken into custody by Indiana State Police after a nationwide Amber Alert.
In the weeks following her disappearance in 2015, hundreds of volunteers joined family members to search for the missing mother,
CBS Philly reported at the time.
According to court documents, Keisha Hamilton was reported missing by her sister, Janell Foster, who told police that she had received worrisome messages from her the night before. She had also failed to show up for work that morning.
Keisha Hamilton had apparently feared for her safety, and told her sister to call police if anything happened to her.
