A 44-year-old man is charged with entering his uncle and aunt's Bloomington home late last week and using various weapons to kill him and leave her critically injured, though a motive in the deadly attack remains unclear, according to charges filed Monday.
Mark Novak, 74, died and Pamela Novak, 72, remains in intensive care following the predawn attack Thursday. Their nephew Adam Roring of Savage is accused of entering the Novaks' home on 105th Street where both were beaten and stabbed. The Hennepin County Attorney's Office charged Roring with second-degree intentional murder and attempted murder.
Pamela Novak called 911 shortly before 5 a.m. Officers arrived and saw her lying on the floor. As they tried to get inside the home, officers heard noises coming from the basement and spotted Roring climbing out a window and attempting to flee, charges say.
Roring remained held without bail at the Hennepin County jail. He has a first court appearance Tuesday and an attorney for him is not yet listed.

According to the criminal complaint:
Roring's jacket, pants and gloves appeared to have blood on them upon his arrest. He also had in his possession a metal bar and part of a blood-covered nunchaku. During the search of the Novaks' home, police found metal links that were likely from the nunchaku and they also recovered a large chef knife in the kitchen sink covered in blood.
Mark Novak suffered a severe laceration to his throat and injuries to his head, face and defense wounds on his hands. He was pronounced dead at the hospital. Pam Novak was treated for injuries to her head, face and neck.
She told police that they were in their bedroom "when they were awoken by a male who kept beating them with an unknown object." She escaped the bedroom and was pushed down the stairs before she was able to call 911 and identify Roring as the assailant.
