PORTLAND, Ore. (AP) - The last of three young men who beat a homeless man who bought them beer has been sentenced.

Officials said 16-year-old Shawn Soldier Glancy of Portland will serve 70 months after pleading guilty Friday in Clackamas County Circuit Court to an assault charge.

Prosecutors said 43-year-old Andrew Gonzalez made a beer run for Glancy and two other underage young men.

In return, prosecutors said, they planned to kill Gonzalez for the thrill of it and then steal his backpack and bicycle.

But a homeless woman camped nearby at a boat ramp along the Willamette River scared them off by yelling that the police were coming.

Authorities said Gonzalez barely survived the beating and stabbing he took.

A 17-year-old from Gresham and a 20-year-old transient have also pleaded guilty. Charges of attempted murder were dropped.
