BILLINGS, Mont. (AP) — A sentencing hearing is scheduled Monday for a man who pleaded guilty to the stabbing death of a Billings photographer and philanthropist who often gave money to people in need.

Prosecutors said 24-year-old Zachariah James Wiseman was high when he stabbed Sample three times on June 19, 2014. Sample died a short time later at a Billings hospital.

The Billings Gazette reports (http://bit.ly/1IFrHnx ) Wiseman pleaded guilty to deliberate homicide in April.

Sample was vice president of the Sample Foundation. His photographers appeared in numerous books and calendars.

Witnesses tackled Wiseman after the stabbing and held him for police. He has been jailed on a $510,000 bond since his arrest.
