TULSA - The Oklahoma State Medical Examiner's Office says the man killed by a Tulsa, Oklahoma, officer died from "a penetrating gunshot wound of chest" and his death is considered a homicide.

But spokeswoman Amy Elliott says a full autopsy report and toxicology results for Terence Crutcher are not yet complete.

Tulsa Police Officer Betty Shelby was charged Thursday with first-degree manslaughter in Crutcher's Sept. 16 death. An affidavit from District Attorney Steve Kunzweiler's office said the officer "reacted unreasonably" when she shot Crutcher, who did not have a gun.

An attorney for Shelby has said the officer believed Crutcher was using the hallucinogenic drug PCP, and a police spokesman has confirmed the drug was found in Crutcher's SUV.

A community college in Tulsa plans a remembrance ceremony to honor a 40-year-old man who was fatally shot by a police officer last week.

Tulsa Community College says a ceremony will be held at noon Friday honoring Terence Crutcher, who was a student there. Crutcher had been scheduled to begin a music appreciation class at the college on Sept. 16, though the course was canceled a day earlier because of low enrollment. President Leigh Goodson says Crutcher brought to the school "his talents, hopes and dreams of creating a successful life by dedicating himself to completing a degree."

Friday's ceremony will include a moment of silence and comments from Oklahoma state Sen. Kevin Matthews, the chairman of the Oklahoma Legislative Black Caucus.
