A massive grid search is being planned for Monday as Florida investigators continue to look for a Hobe Sound mom who vanished nearly two weeks ago.

Tricia Todd, a U.S. Air Force veteran and nurse, was reported missing after failing to pick up her 2-year-old daughter from her ex-husband’s house on April 27, The Palm Beach Post reported. The sheriff’s office has said there’s no evidence linking Todd’s ex-husband to her disappearance.

Todd was last seen in surveillance camera footage from a Publix supermarket on April 26.

Cadaver dogs searched a three-mile stretch but came up empty.

Authorities have not officially ruled Todd’s disappearance as anything nefarious and said there was no evidence of a crime.
