Wei Lin always had a reputation for helping others."He was so kind," said the 28-year-old's wife through a translator. "Whenever his friends needed help, he tried his best to help them."And it was while helping a friend that Lin became the victim of a deadly attack.It happened on May 24 as an employee of his restaurant was making a food delivery in Philadelphia."During the delivering process, he got into a car accident," said the victim's wife, Mrs. Zhang, who only wanted to use her last name due to safety concerns. She spoke with WPVI-TV through a Mandarin translator.The employee who got into a car crash didn't speak English and called Lin to help him communicate with the other driver.Lin's family members say he called the police and exchanged information with the woman who was driving the other car. What happened next was a complete shock."The suspect came out of nowhere," Zhang says of a man who arrived on the scene when police weren't there."It was a fist and a really heavy hit at my husband's head," recounts Zhang of the story the delivery driver told, detailing how a man who was a relative of the other driver approached Lin and punched him in the head."My husband collapsed," said Zhang, who got a call about the incident at the couple's restaurant.She says, initially, it was reported that her husband was involved in the car crash.John Chin, executive director of the Philadelphia Chinatown Development Corporation, substantiates that claim."At the beginning, police just treated it as a fender bender," said Chin. "Our agency notified police and said, 'Hey this fender bender became a very violent incident against a male victim.'"Lin was hospitalized for three days before succumbing to his injuries on May 27. His wife says he was unconscious the entire time suffering from severe brain damage.Police have arrested a suspect, Jose Figueroa of Hunting Park. He's charged with manslaughter.Lin and his wife had a three-month-old and a 19-month-old together. A GoFundMe page has raised more than $100,000 for his family.
