Roseville police officer Joe Adams only learned their names later, in the hours after he shot and killed them.
Wayne Malone. Billy Holt.
Neither man had committed a crime. But both were in the throes of a mental health crisis when police were called for help. The encounters, three years apart, turned fatal when Malone and Holt burst out of their homes, weapons in hand, fighting demons only they could see.
A county attorney and a grand jury determined that the shootings were justified. Adams remains unshaken in his belief that on both nights he did the only thing he could.
"It's a terrible thing," Adams said. "It takes a toll on you mentally, it takes a toll on your family."
At least 45 percent of the people who have died in forceful encounters with law enforcement in Minnesota since 2000 had a history of mental illness or were in the throes of a mental health crisis, according to a Star Tribune analysis of death certificate data, court and law enforcement records and interviews with family members. That's double the estimated rate of mental illness among U.S. adults.
The overrepresentation of the mentally ill in fatal encounters with police is a national phenomenon. The Treatment Advocacy Center, a Virginia nonprofit that advocates nationally for better care of the mentally ill, estimates that people with severe untreated mental illness are 16 times more likely to be killed in a police encounter.
And the deaths are rising. In a 2015 spike, 9 of the 13 people who died statewide had mental health problems. The toll is grim proof that law enforcement agencies across Minnesota are working the jagged edge of a splintered mental health care system, where the most available tool for families facing a psychological emergency remains 911 and a squad car.
