Wednesday marked four years since Jennifer Dulos was reported missing, launching a multiagency investigation that garnered national attention.

The investigation into Dulos’ disappearance spanned multiple areas across Connecticut from a park in New Canaan to a garbage dump in Hartford.

On June 2, her estranged husband, Fotis Dulos, and his girlfriend Michelle Troconis were arrested and charged with tampering or fabricating physical evidence and hampering an investigation.

One week into 2020 Fotis was arrested and charged with murder in connection with Jennifer's disappearance.

Troconis was also arrested and charged with conspiracy to commit murder.

A third suspect, Fotis' civil lawyer and friend, Kent Mawhinney, was also charged with conspiracy to commit murder.

A couple of weeks later, Fotis committed suicide before the case could continue.

Troconis and Mawhinney continue to make court appearances regularly.
