RALEIGH (WTVD) -- Raleigh police said a search of a northern Wake County lake led to the discovery of human remains that could be 2-year-old Tristan Blue.
The remains, which were found in the water off of Creedmoor Road, have been transported to the N.C. Office of the Chief Medical Examiner for further analysis.
Meanwhile, Tristan's father appeared before a judge in Raleigh and was told he'll stay in jail without bond.
Police charged 31-year-old Steven Daniel Blue with murder on Christmas Day.
Tristan Blue was reported missing by his father Wednesday at his home at the Arbor Creek Apartments off Buck Jones Road.
Blue told investigators he last saw the boy at 7:45 a.m. Police were not contacted until 1:15 p.m. Investigators initially said they believed the child may have wandered outside, issued an Amber Alert, and began an intensive search of the neighborhood.
The next morning, Blue was arrested by detectives who cited "probable cause" in an arrest warrant. Further details were not released.
Detectives have also charged the boy's mother - 25-year-old Briana Dangerfield - with child neglect in the case. An arrest warrant alleges she left Tristan alone while she went to work.
Her bond was set at $100,000. It remained the same after she appeared in court Friday.
