Queens psycho ripped neighbor’s lungs & heart out

A psychotic neighbor with a festering rejection complex was arrested for brutally butchering — and stealing organs from — a Flushing woman who owned an employment agency and declined to find him a job, cops said.

Police said the vicious killing was the culmination of a campaign of harassment and assault that maniac Huang Chen, 47, waged against victim Qian Wu since 2006. She took out nine orders of protection during that span.

In a gruesome twist straight out of a slasher film, Chen allegedely ripped Wu’s lungs and heart from her body, and the organs still have not been recovered, police said.

Yesterday, Chen allegedly followed Wu, 46, into her apartment on 40th Road near Main Street and allegedly stabbed her numerous times in the torso before fleeing, cops said.

A woman in Wu’s building called 911 at approximately 7:35 p.m., when she saw blood seeping out of the apartment door, cops said.

Meanwhile Chen, clad in blood soaked sneakers, sought medical attention at New York Hospital-Queens for a gash on his right hand and leg.

He claimed to have sustained the wounds while fighting off a robber during a home invasion, cops said.

Investigators went to his apartment — which is a few doors away from Wu’s — and found surveillance video of him entering his building in bloody clothing and leaving in fresh duds, cops said.

The video also captured his neighbor, Wenxin Zhang, 54 carrying a bag walking a few paces behind him, cops said.

The bag was later recovered in a nearby park and was stuffed with bloody clothing, a knife and hammer, cops said.

Chen had been arrested in May 2006 after punching Wu, cops said. He served 30 days in jail for the attack.

He was charged with second degree murder and tampering with evidence. Zhang was also arrested and slapped with charges of evidence tampering.
