PITTSBURGH (AP) — Prosecutors have withdrawn homicide charges against a Pittsburgh man in a shooting death 2½ years.

The Pittsburgh Post-Gazette reports that 20-year-old Tremond Alston is still being held based on a juvenile detainer with unspecified charges that hasn't been lifted by the courts.

Alston and 19-year-old Charles Williams were charged in the slaying of 25-year-old Chauncy Howard, who was found dead inside a crashed vehicle in January 2016.

The case went to trial last summer but ended in a mistrial after authorities said Williams' father, English Burton, approached a juror outside the courthouse.

Burton later pleaded guilty to jury tampering and was immediately paroled on a three- to six-month sentence.

Alston's attorney, Patrick Thomassey, hailed the decision to drop the charges, saying "My client has maintained all along he wasn't involved."
