Sandra Wisniewski was shot to death by her boyfriend, Gregg Phillips, 25, in the hotel room they were temporarily living in. As she attempted to leave the hotel, he grabbed her, pushed her to the ground and shot her. Gregg then went out into the hallway and fatally shot Anton Uebelhoer, a hotel guest and the first person he encountered. Gregg shot Anton seven times and shot and wounded two other hotel guests. He held another man hostage as he telephoned several people, including his mother. Gregg finally surrendered to a SWAT team after a 30-minute standoff. He was wearing body armor and using an automatic assault rifle throughout the attacks.

Sandra and Gregg were in a relationship for over four years and lived together. According to Sandra’s friends and family, he was physically and verbally abusive toward her. They were staying at a hotel at the time of the murder because Gregg was trying to avoid some men over a money issue. On the evening of the homicide, Gregg was confronted by the men he was hiding from. Following this confrontation, Gregg accused Sandra of setting him up and telling the men where to find him. Sometime after midnight Sandra called a friend very upset and told her that Gregg thought she was lying and that he was threatening her. Her friend tried to calm Gregg down over the phone but he hung up on her. At 2 a.m. Sandra called her sister and said, “I need to be picked up now”. Sandra told Gregg she was leaving and packed a bag of clothes. He shot her as she tried to leave. By the time her sister and cousin were able to get to the hotel it was surrounded by police and Sandra was already dead.

Gregg Phillips was found guilty by a jury of two counts of First Degree Intentional Homicide, Attempted First Degree Intentional Homicide, First Degree Reckless Injury, Taking a Hostage, Felon in Possession of a Firearm. Gregg was sentenced to two consecutive life sentences with 85 years in prison to run concurrent with the life sentences.
