(NewsNation) — The father of a 9-year-old girl found dead in upstate New York a day after she was reported missing has been charged.

Luciano Frattolin, 45, is charged with murder in the second degree and the concealment of a human corpse. Authorities said Monday that a motive was still under investigation.

According to NewsNation affiliate WTEN, Frattolin called 911 around 9:40 p.m. to report his daughter, Melina, 9, as missing with a possible abduction near Exit 22 in Lake George, New York.

The Amber Alert said she was last seen in a white van heading southbound on I-87. Police said as they continued to investigate, they found inconsistencies in Frattolin’s account of events and the timeline he provided.

According to police, Frattolin told them he pulled over on Exit 22 to take a bathroom break. He said when he returned to his car, he found a white van next to his car and two men forcing Melina to get in the van. Police found the allegation to be untrue.

Frattolin and his daughter, both Canadian citizens, came to the U.S. for a vacation on July 11 and planned to return on Sunday, when Melina would be back in the custody of her mother. Frattolin and Melina’s mother have reportedly been separated since 2019.

Police said at 5:30 p.m. on Saturday, Melina was seen on video surveillance with her father outside a restaurant in Saratoga Springs. An hour later, she spoke with her mother on the phone and told her they were headed back to Canada. Melina did not seem to be in trouble on the phone call.

Melina was found dead in Ticonderoga, New York, on Sunday morning. Her cause of death has yet to be determined.

Frattolin reportedly had no prior criminal history or history of domestic violence. His next court appearance is scheduled for Friday.
