Connecticut State Police returned to a park in southwestern Connecticut to search for missing mother of five Jennifer Dulos on Monday, more than two years after she disappeared

Detectives were following up on "previous investigative information" related to the Dulos' disappearance, a state police spokesperson said. 

"This is being done out of an abundance of caution to explore every avenue related to the case," the spokesperson said. "These follow-ups are standard procedure as our detectives thoroughly investigate any and all leads."

Dulos vanished on May 24, 2019, after dropping her five kids off at school. Her SUV was found that day near the Waveny Park that officers were scouring on Monday.

Her remains have still not been found, but authorities arrested her estranged husband, Fotis Dulos, and charged him with murder and kidnapping in January 2020. He committed suicide just weeks later.

State police allege that Fotis attacked Jennifer when she returned home from school and drove off with her body. 

Authorities found bloodstains throughout her New Canaan home and a medical examiner ruled that she was likely killed by "some combination of traumatic, blunt-force injuries such as a bludgeoning/beating, and/or sharp-force injuries such as a stabbing/slashing."

Michelle Troconis, Fotis's ex-girlfriend, and attorney Kent Mawhinney, a friend of Fotis, have been accused of helping him cover up the crime. They are both facing murder conspiracy charges. 

Troconis has pleaded not guilty, and her family released a statement earlier this year saying that "her innocence will prevail in the end."

Fotis Dulos denied that he had anything to do with his wife's disappearance before he committed suicide. One of his attorneys, Normas Pattis, alleged that Jennifer may have faked her own death amid contentious divorce proceedings. 

A Connecticut State Police spokesperson said they do not have plans for additional searches at this time.
