A state court security officer on Friday admitted taking cash payments from bail bondsmen, the latest development in a continuing investigation of the Connecticut bail bond industry.

Jill D'Antona, a judicial marshal employed at the Superior Court on Elm Street in New Haven, pleaded guilty in federal court to soliciting and accepting a gratuity. In her position, which her superiors said she is in the process of resigning, D'Antona, 37, of Seymour, was assigned to courthouse security and prisoner transportation duties.

D'Antona is accused of taking thousands of dollars over at least five years from Robert and Philip Jacobs, two of the three principals in a family-owned bail bond business operating in greater New Haven. The Jacobses, who were charged earlier in connection with the same investigation, have admitted paying D'Antona for using her official position to get them business.
