Prosecution Alleges Premeditated Motive of Jealousy

The state’s opening arguments centered on the theory that the fatal shooting of 37-year-old Matthew Allen Bills was an act of domestic retaliation. Assistant Prosecutor Shane McCullough argued that Cupp killed Bills after discovering he was reportedly cheating on her, citing a relative's testimony that Cupp had previously threatened to kill him under such circumstances. According to the prosecution, Bills was shot three times—in the chest, abdomen, and back—at the Maple Drive residence on March 18, 2025. The state highlighted that a holster matching the murder weapon was found in a purse at the scene, which they intend to link to the defendant.

Defense Claims Survival Instinct and Self-Defense

Defense attorney George Cosenza presented a starkly different narrative, describing the incident as a tragedy rooted in a volatile relationship rather than a crime. According to the defense, Cupp had arrived at the home to collect her belongings after a breakup when Bills allegedly confronted her in a bathroom with a .357 Magnum. Cosenza argued that a struggle ensued, during which both parties were shot. The defense pointed to Cupp’s own severe injuries, including a broken collarbone, a shattered shoulder blade, and a nearly useless left arm, as evidence that she was fighting for her life against an intoxicated and erratic aggressor.

Forensic Evidence and the 911 Dispatch

Both sides referenced the 911 call placed by Cupp immediately following the shooting. While the prosecution noted that Cupp only reported being shot, the defense argued this was the act of a woman in shock and critical condition. According to forensic details shared in court, the firearm found at the scene was covered in blood that could not exclude either individual. The prosecution emphasized the shot to Bills' back as proof of a non-defensive act, while the defense maintained that the chaotic nature of the struggle in a confined bathroom made the trajectory of the bullets consistent with a desperate attempt at survival.
