Massachusetts and New Hampshire authorities on Saturday recovered 5-year-old Elijah Lewis' remains in Abington, Mass., according to Plymouth District Attorney Tim Cruiz.

Authorities spent hours searching for the missing New Hampshire boy between Friday evening and Saturday morning after learning new information regarding his disappearance.

"This morning, state police, a cadaver dog and special emergency response team members located what is presumed to be Elijah's body buried in the ground," Cruiz said during a press conference. "I'm not going to get into the specifics of the crime scene or the manner in which this boy's body was found at this time."

Cruiz added that authorities found Lewis' remains in a "wooded area off of Chesnut Street."

The investigation into Lewis' death is active and ongoing.

The New Hampshire Division for Youth, Children and Families (DYCF) notified authorities of Elijah Lewis' unknown whereabouts on Oct. 14, according to New Hampshire Attorney General John Formella's office, which said in an Oct. 14 press release that Lewis was last seen six months ago.

Officers with the New York City Transit Authority located and arrested Lewis' mother, Danielle Denise Dauphinais, 35, and Joseph Stapf, 30, on witness tampering and child endangerment charges in New York City on Oct. 14, the Formella's office said in a news release on Monday. There was no sign of the boy at the time of their arrest.

The pair allegedly told people they knew to lie about Lewis and where he was living, knowing that child protection services were searching for the boy.
