HAMPTON, Va. -- Authorities confirmed the remains discovered at the Hampton NASA steam plant were those of missing 2-year-old Noah Tomlin.
Hampton police made the announcement Saturday, July 13 following an update from the Virginia Department of Forensic Science and the medical examiner.
The remains were found at the city-owned steam plant in Hampton just before 9 a.m. July 3, nine days after his mother reported him missing from their Hampton mobile home, Hampton Police Chief Terry Sult previously said. The boy's mother, Julia Tomlin, was charged in his disappearance.
City police officers -- suspecting the boy's body may have been taken to the plant or a landfill -- spent days sifting through about two million pounds of garbage by hand, Sult said.
The investigation began June 24 when the boy's mother reported him missing. She initially said her son was last seen when he was put to bed around 1 a.m. She reported him missing that day at 11:36 a.m., Sult said.
In 2010, Tomlin spent five months behind bars after pleading guilty to felony child neglect. Court documents said her then-1-year-old daughter was severely burned after Tomlin sat her down on a hot kitchen stove.
Officers picked through trash in awful conditions
Sult didn't say why investigators started searching the landfill and the steam plant, except that "information gained through the investigation helped focus the search efforts."
City police officers waded through trash in terrible conditions for days, the chief said.
"You're dealing with conditions that are high humidity, high temperature. In this case, at the steam plant, they're in a confined space," Sult said.
Firefighters monitored carbon dioxide and methane levels while officers searched, and called the officers back when the levels rose too high.
"When you get into that, and you smell the odors, and you're in the midst of everything. Then you realize what you're there for, and you're going through literally millions of pounds of garbage," Sult said. "It takes tolls."
