XXXTentacion Murder Suspect BEGS Judge; "Please Save Me From COVID-19!!".

One of XXXTentacion's murder suspects fears he will die from coronavirus while he's behind bars and now he's begging a judge to let him out on bond.

Dedrick D. Williams -- the first of 4 suspects arrested and indicted for the rapper's murder -- has written a letter to Judge Michael A. Usan claiming he's afraid of contracting COVID-19 because his immune system is very weak.

According to docs, obtained by TMZ, Williams gets right to the point in his letter, writing, “I am sending you this letter to save my life.” He claims a deputy at the Broward County main jail infected an inmate with the deadly virus and says he's afraid because he claims nobody's being tested at the jail.

Williams says he's being held behind bars because he violated probation but swears he's innocent of his involvement in the rapper's murder. He's asking the judge to allow him to bond out at least until the pandemic blows over.

Williams ended his letter telling the judge, "I hope that you and your family are safe as well." The judge has not yet made a ruling.
