NEW YORK (WABC) -- There are some wounds that never heal and some scars that never disappear. For 22-year-old Avril Liang, this is her pain of losing her only sibling - her best friend, and not knowing who the killer is.
The Bay Ridge woman says if her brother could hear her, she would ask him one question.
"'How am I doing?' I want to know if I am doing right by everybody, and that I'm doing okay," she says.
Kevin Liang was an FDNY EMT. He was off-duty riding his motorcycle when he was killed by a hit and run driver on the Kosciuszko Bridge. Just 27 years old, his family says he had his whole life ahead of him. He just passed the firefighters exam, and was about to live his dream.
"The best part of his life was in front of him. He was really blossoming into a man. He was very responsible and he had the support of his entire family, his entire community. Everyone was rooting for Kevin," says cousin, Maxwell Li.
Liang was struck around 8 p.m. on Saturday, September 30th. Investigators believe he was hit by a dark-colored Sedan. His family, meanwhile, is frustrated by the pace of the investigation.
"No one has even communicated to them, 'hey we have some leads, we're working on this,' so they're just in the dark. They're trying to call the lead investigator and his cellphone doesn't work. His phone is inactive," said State Assemblymember Ron Kim.
Kim believes there might be clues, but the family doesn't know if they exist.
"You're telling me the governor just spent $550 million on this new bridge, you're telling me we don't have high-tech cameras?" he adds.
Liang's family, meanwhile has a plea.
"Please do the right thing. Be a Good Samaritan. Do the right thing, come and help us - help out. Help Kevin, because we know that he would do the same for you," says cousin, Pang Lee.
Liang's funeral will be held on Tuesday. His family is offering a $25,000 reward for any information that may lead to an arrest. They are hoping this will not only get them the justice they are seeking, but the closure they desperately need.
