A Bibb County jury deliberated just 45 minutes Thursday before finding a Macon man guilty of killing a father and his son last year.

Superior Court Judge Howard Simms sentenced Samuel Lee Pettigrew to life in prison after a jury found Pettigrew guilty of two counts each of felony murder and malice murder, said Assistant District Attorney Brian Granger, who prosecuted the case. Pettigrew was also convicted of possessing a firearm during the commission of a felony, adding another five years to his sentence.

The murder convictions were merged for sentencing purposes.

Pettigrew, 64, lived at a boarding house on Maynard Street, in the Fort Hill neighborhood off Emery Highway, that was owned by 58-year-old Barclay Anthony Sr. Pettigrew told police that he and Anthony got into an argument about the rent. When Anthony and his son, 36-year-old Barclay Anthony Jr., surrounded him, he shot them both.

The elder Anthony was shot several times, while the younger Anthony was shot twice.

Police later found a gun stuffed in Pettigrew’s pillow.
