The Guatemalan who burned a woman to death on a New York City subway is an illegal alien who was previously deported by the Trump Administration in June 2018.

The Guatemalan illegal, Sebastian Zapeta, crossed into the US in Arizona on June 1, 2018 and was deported a few days later on June 7, 2018.
Zapeta then reentered the US illegally as a ‘gotaway’ at an unknown time and location and roamed around freely thanks to Joe Biden.
