The family of a 9-year-old girl feared to have been abducted from an upstate New York park is begging for help as huge search efforts continue for the “trusting” youngster who could now be in “imminent danger.”

Charlotte Sena vanished during a bike ridewhile camping at New York’s Moreau Lake State Park with her family Saturday evening in what Gov. Kathy Hochul called “every parent’s nightmare.”

“I just want my daughter back,” Charlotte’s mother, Trisha, told the Albany Times Union of the “good kid” who is “trusting.”

“We just want her returned safely like any parent would,” her familyalso told NBC News.

“No tip is too small, please call if you know anything at all.”

The young girl was last seen wearing an orange tie-dyed Pokemon shirt, dark blue pants, black Crocs and a gray helmet.

She is described as a white child with blond hair, standing 5 feet 1 and weighing 90 pounds.

Charlotte’s aunt, Jene Sena, said her niece seemed to disappear “into thin air” in a matter of minutes.

“She disappeared almost into thin air. I mean it was, minutes, minutes, between when she was last seen and when she wasn’t there anymore,” the relative told NBC News Monday.

The missing girl’s bike was found on Loop A, with a 100-person search party composed of state troopers, special ops, forest rangers, park police and civilian volunteers converging at the scene.

By Monday afternoon, approximately 400 search and rescue personnel were actively searching — including from the FBI and 34 volunteer Fire Departments, according to the NY State Police.

Police dogs, two drones, two boats and six underwater teams are also scouring the area around the park, while others search near Saratoga Springs.

“She is a highly intelligent, adventurous 9-year-old — but obviously this is out of character for her,” a state police spokesperson, Stephanie O’Neill, told the Times Union, adding that Charlotte had been to the park before but was not overly familiar with it.

The family lives in Greenfield, a town of about 8,200 residents in Saratoga County, where the youngster’s father, David Sena, is a union pipe fitter, and her mother, Trisha, is a food service inspector for Stewart’s Shops convenience stores.

Charlotte is the middle child of three girls.

Following her disappearance, NY State Police Lt. Col. Richard Mazzone said his team conducted an extensive 18-hour search of the park before issuing an Amber Alert. Police now believe the child is no longer there.

Moreau Lake State Park is closed down until further notice as law enforcement continues to search.

Visitors were asked Sunday night to avoid the area, and leave the search efforts to the authorities and professionals.

“Please, also send all love and light to the family, as well as the people searching,” the park said on Facebook.

The governor said Charlotte’s family was left distraught over the sudden disappearance.

“The family was here to make memories, the kind that would last a lifetime. Instead, it turned into every parent’s nightmare,” Hochul said.
