A man accused of stabbing his neighbor to death after a night of drinking left traces of blood and stained clothing in his home and the trash bin behind his work, according to police records.

Jefrey Vasquez-Calderon, 37, was arrested March 1 and charged with the murder of Luis Sanchez. The both lived on Bennington Drive in East Windsor.

Police received a call from a man at 15 Bennington Drive around 8:30 a.m. Feb. 27, who had found his roommate, 30-year-old Sanchez, dead behind their home, according to a criminal complaint charging Vasquez-Calderon with murder. Sanchez had two receipts on him, both time stamped between 1 and 2 a.m. from Exit 8, a local bar and liquor store.

Viewing surveillance footage obtained from Exit 8, police watched Sanchez leave the bar with another man shortly after 2 a.m., the pair getting into Sanchez’s car, police said. The second wore a light colored zip-up Polo sweatshirt, a green striped shirt, dark pants and dark sneakers.

Sanchez’s roommate identified him as “Flaco," whom Sanchez had previously worked with at Diversified Rack and Shelving in East Windsor. The manager of the store told police “Flaco’s” real name was Jose Alvarez, and that Alvarez’s girlfriend worked there, too, according to the document.

But the girlfriend told police her boyfriend’s name was actually Jefrey Vasquez, and that he lived down the street from Sanchez at 46 Bennington Drive, where she had seen him just hours before Sanchez was reported dead. She said she had received a message from her boyfriend, telling her that he was the last person to see Sanchez alive, according to the complaint.

The girlfriend also told police Vasquez worked at the Cranbury Inn, but police did not find him there that Thursday until 10:15 p.m., when a manager contacted detectives to let them know Vasquez had come to work, according to the complaint.

In an interview with police, Vasquez said he was the man in the video, and admitted to leaving Exit 8 with Sanchez, driving his car back to their street. He had walked over to his house to grab some beers and found Sanchez face down, dead, upon returning, he allegedly told police.

But his lunch bag was covered in red-brownish stains, and a zip-up hoodie like the one in the surveillance footage had been dumped behind the inn, according to the complaint.

Vasquez allegedly explained those details by saying the blood had spread to his clothing when he went to pick up his friend. He admitted to trying to wash the sweatshirt before dumping it, along with his sneakers. He threw his pants out at another job, he told police.

Police searched Vasquez’s home, finding blood on the screen door and wall, a knife with a wooden handle on the kitchen counter and a pair of blood-stained pants stashed in the dishwasher. They also interviewed his roommate, who said she cleaned the knife and hid the pants in the dishwasher upon Vasquez’s request. She said he’d told her earlier that afternoon that he “did something bad,” according to the complaint.

The complaint did not reveal a motive for the crime.

Vasquez-Calderon, who is in the country without documentation, was arrested in Trenton by U.S. Immigration and Customs Enforcement (ICE) agents on Feb. 28, before he was charged by East Windsor Police March 1. An ICE spokesman said he is from Guatemala.

“At the conclusion of the criminal case pending against him, to include any potential conviction and prison term, he will be returned to ICE custody for removal proceedings,” New Jersey ICE spokesman Emilio Dabul told NJ Advance Media last week.

Vasquez-Calderon faces charges of first degree murder and unlawful possession of a knife.

Sanchez was a budding artist who moved to Mercer County from Queens, New York, a few years ago, his family wrote on a GoFundMe page seeking money for funeral expenses. He was a “a devoted husband, and a loving father-- a son, brother, nephew and faithful member of our family.”

Vasquez-Calderon has been in Mercer County’s custody since last Wednesday, when ICE agents turned him over. A detention hearing is scheduled in Mercer County Superior Court for Thursday morning.
