FRANKLIN (Somerset) — Bertha S. Dyer, the 68-year-old principal of Mt. Vernon Elementary School in Newark, was still missing as of Friday morning after not having been seen since Tuesday, as details about her disappearance continue to emerge.

Franklin Township police said Thursday there are "no obvious signs" of foul play, according to a report by NJ Advance Media. After Dyer was last seen at the school on Tuesday afternoon, she spoke at length with colleagues at home that night, according to WABC-TV in New York.

Dyer had complained of a headache to her sister while discussing preparations for the new school year, the WABC report said. That report also confirmed that authorities have requested financial information from Dyer's family in an attempt to track her, and have reached out to area hospitals as well.
