NYC man facing murder charges for allegedlly stabbing mother-in-law, teen in drunken rampage: cops

A Queens man is facing murder, arson and weapons charged for allegedly fatally stabbing his mother-in-law and knifing her teen son in a drunken rage this week, authorities said.

Weisheng Chen was hit with six counts of murder, four counts of weapons possession, two counts of arson and four counts of assault Saturday for the alleged rampage, during which he also set their Flushing home on fire, cops said.

Chen, 27, was reportedly going through a divorce and had been drinking before launching the deadly assault just before 4 p.m. Thursday at the home on Smart Street near 45th Avenue in Flushing.

He allegedly stabbed Qiujin Shi, 50, then turned the knife on Shi’s 17-year-old son, stabbing him in the face and armpit, before lighting a mattress ablaze and slitting his own wrists, cop sources said. 

One of the victims ran outside screaming, catching the attention of a nearby Port Authority cop who rendered first aid and called authorities, the sources said. 

The mother and son were taken to NewYork Presbyterian Hospital, where Shi succumbed to her injuries, police said. The teen was last listed in stable condition. 

Chen was hospitalized after the bloody episode, and remained there Saturday, sources said.

Relatives heard a bang and screaming on the day of the mayhem before finding the wounded, bleeding victims.

“I had my VR headset on, so I couldn’t really hear anything in the beginning. But then I heard loud yelling, and then they yelled quite a bit. So I came out to find out what exactly is happening,” said 20-year-old Guqing Zhang. 

“And that’s when I saw them…[the teen] bloodied on the stairs and everyone was panicking…and I went to open the door and I went in [the room] and I saw my aunt on the floor, not moving,” he recalled. “And then they said there was a guy with a knife inside.”

His sister Rouxin Lin, 16, heard an “explosion.”

“I smelled some smoke when I got to the stairs and I saw my cousin sitting on the staircase, bleeding, blood all over his body. That’s all I saw. After that, my brother just told me to go back downstairs. So I just stood downstairs until the police came,” Lin said. 

“They were talking about a divorce, from what I’ve heard. I don’t know why. Like, everything was fine before. This is the first time this happened. I never heard any fighting upstairs. Never. It’s always calm,” the girl continued, and remembered her aunt as a “really kind person” and excellent cook. 

Chen’s arraignment in Queens Criminal Court was pending Saturday.
