Dale Wakefield may plead guilty to two different stabbing crimes in Bucks County court later this week.
The 21-year-old defendant is scheduled to appear before Judge Rea Boylan at 2 p.m. Thursday.
Wakefield is accused of stabbing and killing a 71-year-old homeless veteran last July.
He also is accused of assaulting another inmate at the Bucks County Prison by stabbing him in the face and arms with a ball-point pen.
Wakefield was behind bars without bail on a first-degree murder charge.
Prosecutors said Wakefield stabbed George Mohr more than 70 times with a pocket knife outside the Doylestown train station.
The Bucks County district attorney has announced she will seek the death penalty for Wakefield, who is from Doylestown.
