Fotis Dulos, 51, is currently in critical condition with carbon monoxide poisoning, Tim McKenzie of the Farmington police said at a Tuesday press conference.

Officers performed CPR on Dulos, who was alone at his residence at the time, said McKenzie.

Officers went to his home for a well-being check because he did not show up for a court appearance scheduled for Tuesday.

Dulos was charged with murder on January 7 in the presumed death of his estranged, still-missing wife. He was out on $6 million bond.

After the murder charge was filed, Pattis told PEOPLE: “A preliminary review of the warrant leaves us relieved and saddened. We’re relieved that there was nothing we didn’t expect or have heard about; saddened because it’s obvious the state police really have no idea what became of Jennifer. This remains an open case in our view.”

An attorney for Troconis and Dulos did not immediately return PEOPLE’s calls for comment.
