The knife that was likely used to kill an Englewood couple in their home last week was found in their grown son's bedroom, stained with blood and wrapped in blood-soaked clothing, according to court papers.

Edward Boduch, 71, and Miroslawa Potocka, 72, were found dead in their home on Lafayette Place not far from Englewood Avenue on Saturday morning after their other son asked police to check on his parents because he had not heard from them in three days.

The grisly scene was described in brief, blunt terms in an affidavit outlining the reasons police were convinced that Pawel Boduch, the couple's 43-year-old son, should be arrested in connection to their killing.

"Victims Miroslawa Potacka and Edward Boduch were found dead at approximately 11 a.m. today from apparent multiple stab wounds," the affidavit said. "Inside the bedroom of their son, defendant Pawel Boduch, a blood stained knife that was wrapped in blood soaked clothing that is believed to have belonged to the defendant."

The affidavit offers the most complete description of the details of the crime that authorities have released since the bodies were discovered Saturday.

Police were called to the home by their other son, Gregory Boduch, the affidavit said. Boduch told police that he typically had daily contact with his parents but had not heard from them since last Wednesday.

Boduch and Potocka had two sons, authorities said. According to a public records search, Pawel Boduch has a brother named Przemyslaw B. Boduch. He could not be reached Monday, and calls to his wife were not immediately returned. It could not be independently confirmed that Gregory Boduch and Przemyslaw Boduch are the same person.

Pawel Boduch was charged with two counts of murder and possession of a weapon, and was being held at the New Bridge Medical Center. He joined a hearing at Superior Court in Hackensack on Tuesday from the hospital via phone.

Typically, remote appearances from the jail or hospital are done with a video conference, but the judge opted to tun the monitors off. She explained that prosecutors have filed paperwork to keep him in custody during preparations for his trial.

Pawel Boduch said little during the short exchange. He mostly gave short yes or no answers to the judge's biographical questions. He's scheduled for a detention hearing on Friday that will determine if he remains in custody.

The discovery of Boduch's and Potacka's bodies set off an hours-long manhunt that ended with Pawel Boduch's arrest as he was getting into his father's sedan in the parking lot of an Englewood ShopRite, less than a mile from the house he shared with his parents.

At the home, police found blood droplets that they believe were not from either of the victims. And when police arrested Pawel Boduch they found him with cuts and saw that his shirt was stained with what appeared to be blood.

"The defendant was found to have cut wounds to his chest and right hand," the affidavit says.

The report does not say whether the wounds were self-inflicted or if they resulted from a struggle, but Pawel's pair of glasses was missing a lens. An eyeglass lens was found under his father's body.

"A singleeye glass lens, consistent with the one missing from the defendant's glasses was found underneath Edward Boduch's body," the affidavit states.
