The admitted accomplice in the Connecticut home invasion case has bragged from prison about “taking out” the family’s dad with a baseball bat, according to an ex-girlfriend.

“He was kind of bragging about it,” the pretty brunette ex, Caroline Mesel, tells Inside Edition of accused monster Joshua Komisarjevsky in an interview airing tonight.

“Kind of like, ‘Oh, he was such a big guy but I took him out.'”

Word of the sickening alleged boast comes one day after a New Haven jury convicted Komisarjevsky’s co-defendant, Steven Hayes, for joining in the nightmare of murder, rape and arson that left Dr. William Petit as sole survivor in the deaths of his wife and daughters.

The doctor was able to break free and summon help, though too late to save his family, despite having been clubbed nearly to death with a baseball bat — prosecutors say by Komisarjevsky, who they believe targeted the family after seeing the wife and daughters in a supermarket parking lot.

Petit’s wife, pediatric nurse Jennifer Hawke-Petit, 48, was raped and strangled by Hayes. DNA evidence links Komisarjevsky to the rape of the youngest daughter, Michaela, 11. Both Michaela and her sister, Hayley, were bound to their beds, doused with gasoline, and burned alive.

Hayes, 47, stands convicted of six capital murder charges, and returns to court Oct. 18 for the penalty phase of his trial, during which the same jury will decide if he’ll be put to death under Connecticut’s death penalty.

Komisarjevsky stands trial next year. In an exclusive interview, Mesel tells the news program that Komisarjevsky was desperate to get money after her father moved her and her family to Arkansas prior to the 2007 murders.

Komisarjevsky even mentioned a specific figure, $15,000, as what he needed to move Mesel back to Connecticut so they could begin a life together.

“He’s like, ‘I would even rob a bank, you know, to get money for you,” she told the news program.

Hawke-Petit was ordered to withdraw just that amount in ransom money — $15,000 — when Hayes took her to a nearby bank before bringing her home to murder her.

Asked if she felt any guilt over her unwitting involvement in the deaths, Mesel responded, “I did go though that whole guilt thing, like this is my fault. Maybe if I was in Connecticut, they would still be alive today. Because I could probably have probably prevented it.”

Hours before the home invasion, Mesel had posted a video on YouTube for Komisarjevsky, in which she sang about missing him.

Now, though, Mesel says she hopes he gets the needle.

“I get so mad thinking about it,” she told the news program. “I kind of wish I could do to him what he did to the girls. I kind of wish he could feel what they went through.”

“He shouldn’t be living in a jail cell and still have his freedom and still have his life, when he took those girls’ lives away,” she said.
