The morning Kim Ambers turned 50, her oldest son, Richard Ambers, called to wish her a happy birthday. I love you, he told her.
It was a tradition for the Ambers family members to see one another on birthdays, but Kim Ambers' celebration would have to wait. Richard was working and had a Halloween party afterward. The whole family would go out for breakfast the next day, on Oct. 29, 2016.
There was another call that morning.
"Mom, come over," said Richard's wife.
Kim Ambers rushed to her 31-year-old son's north Minneapolis home, where two police officers told her he had been shot twice in the head at about 5 a.m. She later learned he had spent the evening and morning selling marijuana.
"I was very hurt and destroyed," Ambers said. "I was unaware people died [selling] marijuana. Coming to that reality was rough."
Richard Ambers' murder wasn't an aberration. While no local or state agencies track homicides linked to drug transactions, longtime investigators say Minnesotans are more likely to die during a marijuana transaction than sales involving harder drugs.
"The violence is there with other drugs, but we don't see the homicides associated with other narcotics as we do with marijuana," said Anoka County Sheriff's Lt. Wayne Heath, commander of the Anoka-Hennepin Narcotics and Violent Crimes Task Force. "No one knows why in marijuana it leads to that extra step."
