DETROIT (8/5/10)--A Detroit man was found guilty Tuesday in a U.S. District Court for the murder of an armored-truck guard who was shot to death during a heist at a credit union's ATM in 2001. Timothy Dennis O'Reilly, 36, faces the rare death penalty for the murder of Norman "Anthony" Stephens during the Dec. 14, 2001, robbery at the Dearborn FCU. The penalty phase of the case begins Monday. It will determine whether he is executed or receives the mandatory minimum life sentence in prison with no possibility of parole. The jury deliberated for several hours before returning the verdict, which ended an 11-day trail. O'Reilly and five other men robbed the truck, which was delivering money to the credit union's ATM during the early morning hours, and escaped with $204,000 in cash. O'Reilly was found guilty of conspiring between June 2000 and December 2001 with six other men to rob the credit union; of robbing the armored truck and killing Stephens; and of murder with a firearm during a violent crime. He also was convicted of a June 2003 robbery at a Comerica Bank location. Michigan banned capital punishment in 1847, but courts can impose the death penalty for federal capital crimes such as a murder during a bank robbery.
