SAN FRANCISCO (AP) - The father of a Los Angeles Dodgers fan stabbed to death after a Giants game last week is making a public plea for independent witnesses to contact authorities.
Robert Preece spoke in front of AT&T Park's iconic Willie Mays statue Sunday and said he believes bystanders used mobile devices to record a fight that ended with the death of 24-year-old Jonathan Denver.
A 21-year-old Lodi man suspected of fatally stabbing Preece's son Wednesday was released from jail two days later.
San Francisco's district attorney says police haven't collected enough evidence to charge Michael Montgomery with murder. The district attorney said Friday that police hadn't interviewed any independent witnesses who don't have any connection to those involved in the altercation.
The suspect's father says his son was acting in self-defense.
