Connecticut authorities executed a warrant on Wednesday at the home of accused wife-killer Fotis Dulos as he remained in “dire” condition at Jacobi Medical Center from a suicide attempt.

The search at Dulos’ Farmington mansion — where he was found inside the garage Tuesday — was conducted by Connecticut State Police, though it’s unclear what they were looking for, the local police department announced on Twitter.

The Greek real estate developer tried to kill himself by attaching a hose to his car’s exhaust pipe with the engine running around same time he was due in court to learn whether his bail would be revoked and he’d be tossed back in jail.

Despite his condition, the bail hearing went ahead Wednesday, with the judge ruling Dulos will face re-arrest if and when he returns to court.

The judge also upped his bail by $500,000 — to $6.5 million. Dulos originally posted a $6 million bond on Jan. 9 and was released to house arrest.

The bond, however, was in question after the company that backed it, Palmetto Surety, raised concerns over “imperfections in the collateral” provided by Dulos: his residences in Farmington and New Canaan, according to court papers.

Meanwhile, it was reported Wednesday that a former co-worker and “best friend” of Dulos helped him post his original bond.

Anna Curry, of North Carolina, signed a $3 million promissory note and wrote two checks totaling $147,000 to help cover Dulos’ bond, according to records obtained by the Hartford Courant.

The two had worked together at a New York financial firm, and Curry was with Dulos on Tuesday before his suicide attempt, the report said, citing sources.

“It is my understanding and belief these were old friends who developed a friendship years ago at work and out of loyalty to that friendship she has assisted Mr. Dulos,” Dulos’ attorney, Norm Pattis, told the paper.

“We should all be lucky enough to have such a loyal friend.”
