The report details evidence to back up the board's conclusion, which includes multiple factors that indicate a self-inflicted wound:
Board report released, concluding Suiter took his own life
A portion of the gun barrel was in contact with Suiter's head at the time the fatal shot was fired;
Suiter is right-handed, and the bullet entered the right side of Suiter's head;
The gun that killed Suiter had polygonal rifling, consistent with a Glock, which was Suiter's service weapon;
Suiter's DNA was found inside the barrel of Suiter's Glock and on its surface, meaning that Suiter's weapon fired the fatal bullet. No other DNA was present;
The remains of the fatal bullet are consistent with department-issued ammunition and the firearm issued to Detective Suiter (but could not be confirmed as Suiter's Glock due to deformation of the projectile);
All three spent shell casings found at the scene came from Suiter's weapon;
Blood spatter was found on the inside of Suiter's right dress shirt cuff, indicating that Suiter's hand and arm were in as high a position as was the entrance wound at the time the fatal shot was fired, with blood being expelled into Suiter's sleeve;
Suiter was trained in self-defense in both the military and the police, and specifically was trained to use the gun slide to disable the weapon if attacked;
Trace amounts of DNA, which may be attributed to two officers who carried Suiter from the lot for hospital transport, were found on his person. Apart from that, no DNA other than Suiter's was located on his person;
Medical examiner protocols dictate that suicide should be considered as a possibility in the event of a contact wound.
The autopsy revealed no defensive wounds, such as abrasions on the knuckles, hands or arms, and Suiter was found with his police radio still in his left hand, which is inconsistent with a struggle;
Video from a neighbor's video camera and testimony of two witnesses establish that a suspect would have had a couple of seconds at most to disarm Suiter, shoot him with his own weapon, erase any trace of his presence, and exit the vacant lot without being seen or heard;
Suiter was scheduled to testify before a federal grand jury the following day in connection with the BPD Gun Trace Task Force ("GTTF") corruption investigation;
Suiter was considered a "subject" of that investigation, and another GTTF member had implicated Suiter in criminal wrongdoing; and
Suiter's attorney repeatedly attempted to contact Suiter the afternoon of Nov. 15 to confirm a meeting that evening at 5 p.m., but Suiter ignored the calls and texts.
