Records show she pleaded guilty Dec. 18, 1997, to possession of heroin with the intent to distribute before the late U.S. District Judge Richard L. Williams. She was released on a $5,000 personal recognizance bond pending her sentencing and ordered to surrender her passport.

The day after she failed to show up for her March 24, 1998, sentencing, Williams issued a warrant for her arrest.

Brian R. Stalnaker, a deputy U.S. marshal, said Thursday that Sencion was born in the Dominican Republic and was a legal permanent resident of the U.S. He said initial efforts to locate her in New York failed, and the case grew cold.

Last year, the U.S. Marshals Service was reviewing old fugitive cases and discovered a Facebook account Sencion created in the Dominican Republic, he said.

While the last posting on her Facebook account was made in 2013, investigators ultimately tracked her down after identifying other people appearing on her Facebook page who may have had contact with her.

In May 2017, a request to locate and hold her pending extradition was made through INTERPOL. Then earlier this year, extradition documents were given to authorities in the Dominican Republic and Sencion was taken into custody Aug. 21, Stalnaker said.
