(KAIR)--A Saint Joseph, Missouri man is going to prison in connection with the shooting death of another man last summer.

KQ2-TV reports 20-year-old Dylan Grippando was sentenced to 15-years in prison for the death of 21-year-old Jaiden Drimmel.

Grippando in November of last year pleaded guilty to second-degree murder. As part of the plea agreement, attorneys agreed that he wouldn’t serve more than 15-years. At the time of Monday’s sentencing, Grippando’s defense requested a sentence of 10-years.

Drimmel was killed July 11. Witnesses said he stumbled out of a Saint Joseph home before becoming unresponsive and dying at the scene.

Grippando acknowledged he pistol-whipped Drimmel but said he was shot when the gun went off accidentally. Buchanan County Prosecuting Attorney Ron Holliday last year said the investigation revealed Drimmel was homeless and may have owed Grippando money for marijuana, but added that there wasn't enough evidence to show the killing was intentional.
