Police say a 25-year-old Chinese immigrant has implicated himself in the brutal murder of a woman and her four young children in Brooklyn, New York, over the weekend. <br /><br />Police believe that suspect Chen Mingdong, who is is the cousin of the dead woman's husband, used a kitchen knife to butcher the five late Saturday night in their apartment on 57th Street in Brooklyn's Sunset Park. <br /><br />Chen, 25, had been living with Li Qiaozhen and her family for a week. On Saturday night Li became concerned. She called her husband who was working but he didn't answer, so she tried her mother-in-law in China who in turn contacted her daughter. <br /><br />The daughter and husband arrived at Li's home only to find Chen, whom they didn't know, covered in blood. They called 911.<br /><br />Officers responded just before 11 p.m. and found Chen in the house with a large knife and scissors nearby.<br /><br />Then in a back bedroom they found the four children ages 1 to 9 next to their mother. All had multiple stab wounds to the neck and torso. The children's father returned home from work to the horrific scene.<br /><br />Nine-year-old Linda, 7-year-old Amy and 1-year-old William were pronounced dead at the scene. Five-year-old Kevin and their 37-year-old mother died in hospital.<br />Neighbors reported hearing loud arguments coming from the apartment several nights before the murders. <br /><br />NYPD Chief of Department Philip Banks told reporters Chen had moved to the US from China in 2004 yet still only speaks Mandarin Chinese. <br /><br />Yuan Gao, a cousin of the mother, described Chen as "crazy" and said he kept getting fired from restaurant jobs after only a few weeks of employment. <br />--------------------------------------------------------<br /><br />TomoNews is your daily source for top animated news.
