"He loved his drill team kids," Oveida said.
Neighbors said Scott was known as helpful and would assist others in shoveling snow. One 52-year-old man who lives on the normally quiet block called the killing unnerving.
"I hope the cops catch them," the man said.
Said another: "He was a good man," who helped in neighborhood cleanups and would line dance at block parties.
Chief Inspect Scott Small said Scott was gunned down as he approached the home about 11:20 p.m.
"He was killed within feet of his front door," Small said. "Family members came out after they heard the shots and saw that it was him."
Scott was thought to be coming home from work, but police have not confirmed that report. He was declared dead at the scene about 11:30 p.m.
Scott was a drill master for the team, and acted as a mentor for children.
"From day one, Gregory was known as a survivor and one to fight for the causes he believed in," according to his biography attached to the drill team website. "Always being advanced in life, he started work at the tender age of ten stocking the soda machine for Miss Pat's restaurant. He moved on to be an usher at the Locust Movie Theater."
Gregory said his goal was to help "young and old people alike" and went on to help recovering addicts at Gaudenzia Drug & Alcohol Rehab.
The family members inside the home were taken to the Homicide unit as part of the investigation, Small said.
Police did not have suspects or a motive as of early this morning.
Neighbors said they didn't hear any fight or altercation outside Scott's home before they heard the shots fired.
