Dr. Frank was found dead on campus at 10:30 p.m. When police arrived, they discovered he was shot. Around his body, police found several expended shells and several bullets that appeared to have missed him.

Upon closer examination of the body, crime scene techs found a note in his pocket that read, "meet me on campus at 10 p.m.,". When investigating Dr Frank's phone record, four suspects came to light: Leo, Michelle, TJ, and Akshita.

While searching the campus for evidence, the police found a Smith and Wesson handgun in a trash can on the other side of campus. When investigators sent the weapon to the lab, it was test-fired, and forensics compared a shell from the scene to the shell from the test firing. Investigators also learned that TJ owned a Smith and Wesson handgun. TJ's gun was seized and also sent to the lab to be test-fired. Using the evidence below, determine if either weapon is possibly the murder weapon.
