Exactly one week after 27-year-old Maryrose Fealey was killed, new information concerning the investigation into her killing is coming to light.

Fealey was from Somerville and was found outside her home around 10 p.m. last Tuesday with multiple stab wounds. Her accused killer, David Shroitman, is now in Somerset County Jail.

The police investigation revealed that Shroitman was allegedly found in possession of a step-by-step plan on how he was going to take her life. It’s part of evidence police found and collected inside his apartment at Brookside Gardens, which sits less than a mile from the crime scene on North Bridge Street.

Shroitman is also 27. News 12 New Jersey has confirmed the two graduated from Somerville High School together as part of the class of 2014. However, police have not confirmed if the two were recently in contact and to what extent.

Police have revealed that inside Shroitman’s apartment, they found bleach, latex gloves and blood near the bathroom and entrance to the home. There was also clothing police believe Shroitman was wearing on the night of the killing. The clothing, police say, was covered in bleach.

The investigation revealed that with the help of surveillance cameras from a home along East Cliff Street, police spotted a person, believed to be the accused, running and getting into a car on the night of the killing. That camera was sitting right behind the victim’s house on North Bridge Street.

An affidavit states that on Sunday, police were called to a business on the report of a suspicious person. It was there that they found Shroitman wearing latex gloves and cleaning his vehicle. Responding officers said they could smell bleach by the driver’s side door.

Shroitman would be arrested the next day and charged with murder, weapons possession and tampering with evidence. A motive for the murder has not been revealed.

A funeral service for Maryrose Fealey is set for Wednesday in Somerville.
