Missing toddler Quinton Simon's mother was arrested Monday for murder – nearly two months after the one-year-old vanished from the family's Savannah, Georgia, home under mysterious circumstances, officials announced.

Leilani Simon, 22, is enroute to the Chatham County Detention Center, where she will be held while she awaits a bond hearing, the Chatham County Police Department announced in a statement on Facebook.

No additional arrests are expected, police said. 

Simon reported Quinton missing Oct. 5, 2022, and days later she was named the prime suspect in his disappearance and death.

"Since that time, millions of people have followed Quinton’s case and have been awaiting answers," the police said in the statement. "We are deeply saddened by this case, but we are thankful that we are one step closer to justice for little Quinton."

Simon is charged with murder, concealing the death of another and falsely reporting a crime, records show.

Chatham County Police Chief Jeff Hadley said at an Oct. 13 press conference that they believe Quinton's remains were discarded in a "specific dumpster at a specific location" and taken by "regular means" to the Waste Management landfill.

The toddler's babysitter, Diana McCarta, previously told Fox News Digital that she believes the child may have accidentally drowned in the family's pool.

Investigators, including specialists with the FBI, spent weeks combing through the landfill in search of the little boy's remains – a process that the police called "more grueling than anyone could have imagined."

As officials painstakingly combed through the city's trash Oct. 18, Simon's mom, grandmother and friends were spotted at Sting Ray's on Tybee Island downing top-shelf tequila shots.

"They were having a great time, like they didn’t have a care in the world," a server told the New York Post. "They were drinking Patrón shots in the deck area, being loud and laughing. It’s almost like they were trying to draw attention to themselves."

Quinton was last seen inside the family's Buckhalter Road home in Savannah, where he lived with his siblings, his mom, his mom's boyfriend and his maternal grandparents, authorities said. 

Simon called police at 9:40 a.m. and reported her son missing. Simon's grandmother, Billie Jo Howell, had custody of little Quinton. Simon has two other children who were since placed in foster care.
