The FBI offered a $25,000 reward for information leading to an arrest in the disappearance of an 11-year-old New Hampshire girl. A private citizen is offering a $5,000 reward for information leading to the girl's return.

"We are still aggressively, aggressively searching and hoping to bring Celina Cass home," FBI Supervisory Special Agent Kieran Ramsay said Saturday.

100 investigators went door-to-door this week in search of Cass, said Ramsey. West Stewartstown, a town bordering Vermont and Canada with a population of 1,000, has been desperately and to no avail putting up posters of the girl.

New Hampshire Senior Assistant Attorney General Jane Young said that authorities have received several tips and are closely evaluating each one.

"We are going to stay with this to locate this lost child," New Hampshire State Police Col. Robert Quinn told reporters Saturday.

Celina was last seen on her computer in her room at 9 p.m. Monday, said police. When her parents woke up, she was missing, WMUR reported.

Celina weights about 95 pounds and is 5 feet 5 inches tall with long brown hair and brown eyes. She was last seen wearing a pink shirt, pink pullover, and blue shorts.

An Amber Alert has not yet been issued.
