Summary based on the NamUs case record (MP78132) and 8 other sources
On the evening of March 30, 2015, a 37-year-old man named Kailong Chen was ending his workday in the Sunset Park neighborhood of Brooklyn, New York. A familiar figure in the community, he was last seen on his store's security camera footage at approximately 11:00 PM as he was closing up his business, a cleaners located at 8123 5th Avenue. Earlier that evening, around 9:00 PM, he had spoken to a reporter on the phone. Mr. Chen was wearing a black coat and light blue pants at the time. His failure to return home that night was unusual and sparked immediate concern among those who knew him.

When Kailong Chen did not arrive home, and with no word to his family, he was reported missing. His disappearance was described as being out of character, as there was no indication that he would voluntarily leave without informing his loved ones. The New York City Police Department's Missing Persons Squad launched an investigation, conducting searches in the Sunset Park area and interviewing family, friends, and anyone who might have had recent contact with him. Investigators looked into various forms of evidence, including phone records and surveillance footage from the vicinity, but these efforts did not yield any significant leads or provide clear answers as to his whereabouts.

As time stretched from days into weeks and then months, the absence of Kailong Chen left a void in his community. His family, holding onto hope, made public pleas for any information that might lead to his return, distributing missing person flyers throughout the neighborhood. Despite these heartfelt efforts and the ongoing police investigation, no substantial breakthroughs have occurred in the case, and there have been no signs of foul play. The investigation into what happened to Kailong Chen after he closed his store on that March night remains open, leaving his family and community with unanswered questions and a sense of unresolved loss.
