An estranged husband claims he "blacked out" when he saw a man in his wife's bedroom shortly after 11 p.m.

Then he started shooting.

He fired multiple shots at the man, hitting him in the thigh, hand, arm and stomach. Then, as his wife fled the scene, he gave chase, shooting her down on the front porch steps of a neighbors home.

Those details and more were provided in an affidavit released Tuesday that describes the gruesome scene that took place late Sunday night on Mirror Place in Jefferson Township, where John Formisano — a 24-year veteran of the Newark police — took the life of Christine Formisano, 37, after chasing her to a neighbor's home.

The affidavit details that the wife, identified by the Morris County Prosecutor's Office, spoke to Formisano on the phone shortly before he broke open a bedroom door and opened fire, striking a 40-year-old man identified only as "T.S."

Christine Formisano was heard yelling, "He's got a gun," and "Call 911," shortly before shots were fired, T.S. told police.

The affidavit states that John Formisano said he was there to drop off glasses for one of their children, when he suspected that Christine Formisano had a male visitor in the bedroom.

"T.S. reported that C.F. spoke to Formisano on the telephone after which she told T.S. that she saw a flashlight and that Formisano was there," states the affidavit, which identifies Christine Formisano as "C.F."

Once Christine Formisano realized that John Formisano was in the house, she closed the bedroom door and locked it behind her, according to the affidavit. Shortly after, John Formisano broke the bedroom door and shot at T.S., striking him in the abdomen, thigh and arms.

John and Christine Formisano's children, who were not named in the affidavit, were nearby when T.S. was shot, the affidavit says. After T.S. was shot, Christine Formisano fled to two of her neighbors' houses on Mirror Place, trying to get in.

A witness saw John Formisano on the property of one of the houses Christine fled to, and saw him fire a handgun, the affidavit says.

Christine Formisano was found dead on the front steps of a neighbor's house, with gunshot wounds to her abdomen, arm, leg and head, according to the affidavit.

Hours later, at 1:30 a.m. Monday, John Formisano surrendered during a motor vehicle stop on Foxcroft Drive in Livingston, 30 miles from the crime scene, Livingston police said.

At that stop, he told officers that he was at the home to drop off glasses for one of his children and entered the house, when he suspected that Christine Formisano had a male guest in the bedroom.

Then he "blacked out" and starting shooting, the affidavit says.

The affidavit paints a picture similar to what nearby residents said they heard that night — multiple shots fired and Christine running down the street, screaming for help.

Neighbors also described a tumultuous breakup between John and Christine Formisano, one that turned "ugly." It is stated in the affidavit that T.S. knew that Christine and John Formisano were finalizing their divorce.

John Formisano was charged with murder, attempted murder, unlawful weapon possession and endangering the welfare of a child.

Court documents show that John Formisano filed for divorce in state Superior Court in Morris County on June 7, citing "irreconcilable differences." The two were married on Dec. 18, 2010.

"For the six consecutive month period immediately next preceding the commencement of the within action, irreconcilable differences have caused the breakdown of the marriage which make it appear that the marriage should be dissolved and that there is no reasonable prospect of reconciliation," divorce records say.

The complaint does not go into detail as to what happened during the months leading up to the divorce.

An attorney for John Formisano in the civil case did not respond to a request for comment.
