The man who allegedly confessed to strangling a cabbie in a fare dispute and then dumping his body in a city reservoir upstate is an illegal migrant from Guatemala, The Post has learned.

Santos Paulino Vasquez-Ramirez illegally crossed the border in 2013 at Hidalgo, Texas, under President Obama, and later ignored a final removal order issued in 2016 under the first Trump administration, according to sources and US Department of Homeland Security officials.

He “should’ve never been in our country in the first place and provided the opportunity to gruesomely take the life of Aurelio Zhunio-Orbez,” Assistant Secretary of DHS Tricia McLaughlin told The Post.

“Open border policies have deadly consequences. ICE lodged a detainer with local authorities to ensure this criminal illegal alien is never allowed back into American neighborhoods. Under President Trump and Secretary Noem, ICE is targeting the worst of the worst,” she added.

In a tragic irony, the cabbie was a legal immigrant from Ecuador.

The accused killer — who was photographed by The Post last week grinning in the back of a patrol car — has at least three prior arrests on his rap sheet, including two DWIs and a criminal mischief for breaking a deli window, according to the Putnam County Sheriff’s Office.

Vasquez-Ramirez, 27, confessed to barbarically throttling Zhunio-Orbez, 65, in a chokehold after the hack picked him up at the Brewster MetroNorth station in Putnam County, according to the county sheriff’s office.

The two didn’t know each other personally but coworkers said Vasquez-Ramirez had hired the victim — who drove for a car service — several times in the past, and the two apparently beefed over a recent fare. A trip from the Brewster MetroNorth station to the suspect’s home in Pawley costs about $40.

On Dec. 1, some time after 11 a.m., Vasquez-Ramirez hired the cabbie — but this time settled the score, cops said.

After allegedly killing the Connecticut father of four in his black Toyota Sienna, authorities said Vasquez-Ramirez dragged the victim’s body into the woods near the Croton Falls Reservoir, which is part of NYC’s water system.

He then stole the cabbie’s minivan and abandoned it near the Purdy’s MetroNorth station, cops said.

A fisherman found Zhunio-Orbez’s body a week later, floating in the massive reservoir.

Zhunio-Orbez worked for Orbe’s Taxi Service, which is owned by his cousin Homero Orbe, who mourned his loss. “I never had a brother. He was like a brother to me,” Orbe said. “It hurts my soul that he had to die like this.”

The driver and fare had an unusual interaction, Orbe said.

“One driver, who was working that day, told me it took a while until [Vasquez-Ramirez] got into the car. The driver saw Santos walking up to the window of the car, he talked to Aurelio — they were negotiating something, and then he walked off again,” Orbe said. “Back and forth for a while. Until Aurelio oepend the automatic door, the guy got in and they left.”

The exact details of the dispute are unknown, but colleagues said Zhunio-Orbez, a missionary leader at his local Mormon church, was not the type to fight over a fare.

“He once told me about a female customer who had lost her wallet and couldn’t pay her fare he said, ‘Ok, mamacita, don’t worry,’” a female cabbie, who chose to remain anonymous, told The Post.

Vasquez-Ramirez — who being held at the Putnam County Jail on murder and robbery charges — is known amongst cab drivers in Brewster, many of whom, like Zhunio-Orbez, wait for commuters at the local MetroNorth station.

“He was a regular client. Our cab company also drove him, but we never had any issues with him,” the female driver said.

Some neighbors feared the suspect. “I don’t want MS-13 gang members to come after me,” one said before shutting their door.

The Putnam County Sheriff’s office said that Vasquez-Ramirez has no known gang ties.

Zhunio-Orbez worked as a cab driver in the northern suburbs for the past four years while living with his family in Danbury, according to an obituary. He loved country music, watching Western films, and playing with his dog. He is survived by life partner and the mother of his kids Irene Fernandez, four children, one grandchild, and six brothers and sisters.
