Today marks the second anniversary of the murder of Joanathan Rosado, a beloved young coach at Legacy Youth Tennis and Education. Jon died in the arms of his parents - Sita and Jimmy - on the front steps of their Hunting Park home after returning from a friend's graduation party.

His death at age 22 was a shock: He had never been in trouble, never even been arrested. Police believe robbery was behind the three bullets that took his life. His unsolved murder is one of many that could be put to rest if just one person would come forward - not to snitch, but to give his parents and sister, Erica, a measure of peace.

Meantime, those who loved him have not forgotten his passion for tennis and his belief that it could change the lives of the hundreds of kids he coached around the city. Nor will they let the bullets that took his life also take their memories of his kindness, talent, generosity and humor.

So today, they'll honor his memory with a moment of silence: At precisely 4:10 p.m., all activity will stop at Legacy's multiple programs throughout Philadelphia, Camden and Chester, to recognize the role that coaches play in the lives of children.

"Legacy invites its students, parents, alumni and the larger community of sports-based youth-development programs to join them in this moment of silence, wherever they're located, to reflect on the impact of coaches and mentors in the lives of studets," said Legacy CEO Lance Lee in a statement.

"While Jonathan was taken from us two years ago, his legacy remains strong and influences both the children he coached and those at the organization today."

Legacy's tennis courts at Hunting Park were dedicated in his name in July 2015.
