PEORIA, Ill. (AP) -- The last of four college students convicted in the death of a Bradley University soccer player has been released from jail.

Twenty-two-year-old Ryan Johnson served a six-month sentence in the Peoria County Jail before his release Friday.

He had pleaded guilty to involuntary manslaughter in the August 2007 death of 19-year-old Sheridan "Danny" Dahlquist, his teammate and roommate.

Dahlquist died of carbon monoxide poisoning and smoke inhalation after the four men lit a Roman candle under his bedroom door.

The other three were released earlier this week.

Police say all five had been drinking.
