The illegal immigrant convicted of killing DC intern Chandra Levy — who then had his verdict overturned — has been deported back to El Salvador, officials said Monday.

Ingmar Guandique had been found guilty in the 2001 death of Levy, 24, but the verdict was tossed because the informant who said the suspect confessed to the killing was found to have lied.

Prosecutors had argued that Levy’s death fit a pattern of previous attacks Guandique committed on female joggers. At the time, he was serving 10 years in prison for attacking two other women in the same Rock Creek Park.

Guandique, who illegally entered the US a year before Levy’s murder, was deported Friday, authorities said.

“Mr. Guandique unlawfully entered the United States, and once here, continued to violate U.S. laws by assaulting innocent victims,” said US Immigration and Customs Enforcement spokesman Matthew Munroe in a statement. “As a result of his actions, he has been removed to his home country of El Salvador.”

ICE added that Guandique, 35, is a documented member of the infamous MS-13 gang.

Levy’s slaying captured national attention, with reports surfacing that she had an affair with then-Democratic US Rep. Gary Condit.

Condit, a California Democrat, was ruled out as a suspect, and authorities eventually turned their focus to Guandique.

Levy’s body was found one year after her disappearance.
