Reward: The Murder of Phil Antonino

Phil Antonino was the owner of Muffler Exchange in Pembroke Park, Florida. He was also my friend for the past 15 years. Phil was the nicest, most generous soul you could meet and would lend a hand to anyone in need. He was an Italian immigrant who came to America, and worked hard his whole life to provide for his family. He was a stand-up guy. 
On 09/22/17, Phil was walking to his business when he saw someone bullying an elderly homeless man. Typical Phil, he would not stand for it and stepped in. Phil was shot to death by this coward. He lost his life protecting the weak, standing up for what is right. His life was taken by a selfish criminal who has brought suffering to the world. I spoke with Phil shortly before his life was taken, and he was, as always, kind hearted and happy.  As his friend, I grieve for him and his family. As a police officer, I cannot rest until his killer is captured. 
Right now, The Crimetoppers Tip reward is only $3,000. I am asking anyone who can donate to please do so to increase this reward, which will hopefully lead to Phil's killer and bring a small measure of peace to his family. If the funds are not utilized in the capture of his killer, they will be donated to Phil's wife, Anna. Thank you for any help you can give.
