Ceiling fans spun quietly above a Schleicher County courtroom, as a San Angelo man faced charges Friday in a fatal hit-and-run that killed a developmentally disabled woman.

Relatives of both Michael Gary Keene and Gisele Rene Jarmon, about 20 people, showed up to hear the case on the third day of trial.

The building’s aged-wooden floor and plastic chairs creaked whenever someone moved.

Keene, 23, is accused of manslaughter and accident involving death after police found Jarmon, 23, dead in the eastbound lanes of the Houston Harte frontage road's 4500 block June 16, 2015, court documents state.
