In the early morning hours of December 16, 2022, the life of 32-year-old Alexandra Lee Pennig was cut short in her downtown Saint Paul, Minnesota apartment. Responding to a distressing 911 call made by her boyfriend, 44-year-old Matthew Ecker, police arrived to find a tragic scene. Ecker, a family nurse practitioner from Fergus Falls, claimed that Pennig had shot herself in the head.
Officers discovered Pennig in the bathroom with a gunshot wound to the left side of her head.
A handgun was found on her chest, with her left hand resting on top of it. Ecker told authorities that he and Pennig, with whom he had been in a two-year open relationship, had returned to her apartment after visiting several bars. He alleged that within minutes of being home, Pennig took his gun from his backpack, loaded it, and then locked herself in the bathroom after a brief, strange exchange. He claimed to have heard a "pop" just seconds after she closed the door, and that he then forced the door open to find her on the floor.
However, investigators at the scene quickly grew suspicious of Ecker's account. They noted that the blood in the bathroom had already dried, which seemed inconsistent with the timeline Ecker provided. The handgun on Pennig's body appeared remarkably clean, with little to no blood on it, and she had no obvious blood on her left hand. Furthermore, family members confirmed that Alexandra was right-handed, making a self-inflicted gunshot wound to the left side of her head questionable. Another key piece of evidence that contradicted Ecker’s story was the bathroom sink; he claimed to have washed his hands after finding Pennig, but first responders noted the sink was completely dry.
The investigation deepened, uncovering more inconsistencies. A crucial discovery was a small metal piece from the bathroom door's lock found underneath Pennig's head. This suggested to detectives that the door was forced open before she was shot and fell to the floor, not after, as Ecker had claimed. This led to the theory that Pennig had locked the door to escape from Ecker, who then broke in and shot her. Ecker was subsequently arrested and charged with second-degree murder.
The case went to trial, where the prosecution argued that the physical evidence pointed to a homicide staged to look like a suicide. The defense maintained that Pennig was distraught over issues with another boyfriend and had taken her own life. In February 2024, a jury found Matthew Ecker guilty of second-degree intentional murder. He was later sentenced to 30 years in prison for the murder of Alexandra Pennig.
