Charlene Schwartz, 34, was found dead in a pool of blood in a north Phoenix hotel room on April 18, 2015. She was not a registered guest but had been visiting someone; her car was in the parking lot with two dogs locked inside. Paramedics pronounced her dead shortly after they were called to the scene.

Investigators focused on Charlene’s husband, 34-year-old Michael Anthony Schwarz of Chandler. Witnesses said Michael checked into the hotel the night before with another woman. Charlene was seen in the lobby late that night and tried to get a key to Michael’s room around 2:30 a.m. After being denied, she was later seen arguing with the woman who had been with Michael. Staff reported overhearing a dispute between Charlene and Michael from inside the room by 4:30 a.m., and one witness said she heard a gunshot from the bathroom before Michael and the other woman left.

Michael was arrested at his Chandler home at about 10 p.m. on April 18 on suspicion of second-degree murder. Does anyone have information about Charlene’s movements at the hotel that night or about the people seen with Michael?
