Wayne Sparrow, who played basketball with Tarver at St. Frances, described Tarver as "playful" — not the type of person to be involved in the crime police described.

"This is quite shocking to me," said Sparrow, 21. "Eddie was so calm and so mellow around people. He never had a grudge or anything."

Tarver played through his senior year at the independent Catholic high school in East Baltimore's Johnston Square neighborhood in 2011.

Tarver pleaded guilty in September 2011 to possession of a stolen handgun and was sentenced to two years of supervised probation, online court records show. He also faces drug possession charges in Baltimore Circuit Court and first- and second-degree assault from a Jan. 21 incident in Washington County.

Court records show that Scott, the victim, also known as Davon Greene, was charged in July 2011 with a killing that occurred March 29, 2011. Scott was charged with first- and second-degree murder and related counts and was acquitted of all charges by a jury in late October.

A woman who answered the door at Scott's house Sunday declined to comment.

Less than a block from Scott's house, churchgoers from Solid Rock Apostolic Faith Church were gathered, after a service, on the sidewalk where young boys — wearing pressed shirts and slacks and dress shoes — raced one another up and down the street.

James Ellis, and his wife, Diana, of Pikesville, said Baltimore violence needs a solution: City neighborhoods need more police on foot patrols, more security cameras and more recreation centers for children to play. But more than that, James Ellis said, community members must be invested in programs that can have a positive impact on young people and their families.

"It's a lack of hope; they don't see a vision for their future," Ellis said. "What they see is right there before them. They need to see opportunity."

Said Diana Ellis, "There are lives ending early every day, either by death or jail."

At their church, Monica Bland runs a program, Advancing Minds Striving for Success, where children and teens grow flowers and vegetables. Together, they plant the seeds in a garden next to the church. Then, they harvest them.

"People must become stakeholders in their community," said Bland, of the Evergreen neighborhood.

The Rev. Barbara A. Abraham of Solid Rock said Friday's shooting is "very disturbing."

"Our young people need guidance," she said. "They need somewhere where they can get some hope."
