A missing Massachusetts girl thought to have possibly run away to the Seacoast region was found safe in New York City Thursday.

Colleen Weaver, 16, left her Raynham, Massachusetts, home between 1 a.m. and 4 a.m., on October 18, and had no contact with her family since, Raynham Police Chief James Donovan said in a statement. It was thought she had traveled somewhere within a 100 mile radius of home, which included the Seacoast region and southern Maine.

Late Thursday night, Weaver was found in New York City by the NYPD and FBI, according to Donovan.

“We are very glad to have found Colleen and that she’ll soon be reunited with her family. This was the best possible outcome we could have hoped for and I want to commend the tireless efforts of our dedicated officers and our partners in the NYPD and FBI who helped to locate her," the chief said. "This has been a trying couple of weeks for everybody involved and I want to thank everyone who assisted in this tremendous effort.”

Donovan did not disclose what led the teen to New York.

The chief said earlier Thursday that Colleen's mother, Kristen Weaver, believed she may have met up with a person she met online because her judgment is affected by neurological issues.

"She doesn't sense danger very well, so she is very trusting, and that's very dangerous," Kristen Weaver said at a press briefing earlier Thursday.
