Marvin Roberts, who was 16 at the time of the 2017 Spring Garden shooting, pleaded guilty Friday morning to 1st-degree murder, robbery, conspiracy and related charges in the death of 38-year-old Gerald Grandzol. He was given the mandatory minimum sentence under a plea agreement with the Philadelphia District Attorney's Office.
"..........Grandzol was killed in September 2017 outside his home on the 1500 block of Melon Street. He had spent the evening at Fairmount Park with his 2-year-old daughter and the family dog. They played Frisbee while Grandzol's wife stayed home with their 5-week-old baby. She was still recovering from a C-section and had barely slept the night before.
Lurking outside the home were the Roberts brothers. They had plans to rob someone that night, prosecutors said. Marvin Roberts owed money to a drug dealer.
Grandzol pulled into a parking spot as the brothers approached him. They wanted his wallet and car keys. Grandzol complied but asked to retrieve his daughter from the back seat.
"We don't care," Marvin Roberts said, according to prosecutors. Then, he shot Grandzol twice in the head.
His little girl screamed and the brothers took off running towards the nearest SEPTA station. Surveillance video showed them laughing, prosecutors said. Kristin Grandzol recalled hearing the shots, going outside, seeing a man on the ground and hearing her daughter's shrieks.
In court Friday, the widow described seeing her husband's "distorted face, choking on his own blood."
Her daughter "witnessed something that night men who go to war never see," Kristin Grandzol said.
"This is what was happening while the defendants laughed," she said...."
Marvin Roberts had a prior juvenile criminal record, and cut off his ankle monitor sometime before killing Grandzol. His lawyer, Eileen Hurley, described him as a "young man who had a very traumatic, chaotic and neglectful 16 years."
Roberts' guardian at the time of shooting was his 20-year-old sister, who had a child of her own.
