More than two-and-a-half years after Jennifer Dulos went missing, police continue to look for her body, and on Monday state investigators searched a corner of Waveny Park. The New Canaan mother of five was murdered by her estranged husband in May 2019 after dropping her kids off at school, officials have said. Though Fotis Dulos was charged in the capital crime in January 2020, he killed himself about three weeks later without disclosing the location of her remains. On Monday morning, state detectives and their search dogs could be seen gathered in the southwest corner of the “mulch pile” off of Lapham Road. An open area where the town long kept ground-up leaves and debris in neat rows, the mulch pile has been available in the past to town residents seeking to pick up mulch for use on their own properties.
