Aguilar faces one count of conspiracy to tamper with evidence and two substantive counts of tampering with evidence.

She could get up to 20 years in federal prison for each count upon conviction.

The indictment alleges that from April 22, 2020, through July 1, 2020, Aguilar conspired with Robinson to corruptly alter, destroy, mutilate and conceal evidence, including the victim’s body in order to prevent Robinson from being charged with and prosecuted for any crime.
