BALTIMORE (AP) — Ten months after the mysterious death of a Baltimore police detective, an investigative review board has concluded that he most likely killed himself.

The seven-member panel says the evidence they've reviewed "does not support anyone other than Detective Suiter himself firing the fatal shot."

They say the gun barrel was in contact with Detective Sean Suiter's head when the shot was fired and nobody else's DNA was found on his service weapon.

When Suiter died last November, a day before he was to testify to a grand jury investigating corrupt colleagues, police and the medical examiner's office called his death a homicide.

The report was released Tuesday. But the findings suggesting Suiter wasn't killed by an attacker were announced earlier this week by a lawyer for his widow.
