AP Newsbreak: Stabbed Fan's Dad to Speak The father of a Dodgers fan fatally stabbed Wednesday during a melee following a Giants baseball game is planning to make a public plea for witnesses after San Francisco's district attorney said he lacks evidence to charge a suspect who has been released. A family member said the victim's father plans to speak outside the Giants' stadium before the scheduled 1:05 p.m. PDT Sunday game with the San Diego Padres. The suspect, Michael Montgomery, 21, was released from custody Friday night after District Attorney George Gascon said police had insufficient evidence to charge him in the death of Jonathan Denver, 24. Gascon said police had not spoken with any independent witnesses who may have witnessed the fight Wednesday night. The victim's father, Robert Preece, believes someone may have recorded the melee with mobile phones, said Preece's sister Jill Preece Haro. "We have reason to believe someone recorded this," Haro said in a phone interview, adding that Denver's father and others with him saw bystanders were using cellphone cameras. We're calling on them to come forward to help both families find out what happened. Haro said the victim's father, who works as security guard at Dodger Stadium, and other family members were motivated to travel from his Southern California home to make his public plea after Montgomery's release and Gascon's explanation for not charging Montgomery. "The San Francisco Police Department has provided us an initial investigation," Gascon said in a written statement Friday night. However, not all witnesses have been interviewed, nor have any independent witnesses of the incident been interviewed. We have requested this and other evidence be collected before we can make an assessment on whether charges should be filed. The San Francisco Police Department didn't return phone calls Saturday. Haro said Freece and the family have not finalized the time and precise location where the father plans to issue his call for witnesses to come forward, but it will be outside AT&T Park. "This is how he wants to address the media," said Haro, who said she divides her time living in Pittsburgh, Pa., and Covina, Calif. We are still formulating a plan, but we're coming up. Denver was stabbed to death after attending the game with his brother, father and two others to celebrate his father's 49th birthday. Denver lived in Fort Bragg, a Northern California city about 170 miles north of San Francisco. The group, many wearing Dodger garb, left the park after the 8th inning for a nearby bar. At some point, they got into a shouting match over the Dodgers with Montgomery and a few friends who were bar-hopping in the trendy South of Market area. At least one was wearing a Giants cap. Police Chief Greg Suhr said. Suhr said Montgomery made "incriminating statements" that led to his booking the night after the stabbing. Montgomery's father told the Lodi News-Sentinel that his son was jumped during the fight, and he stabbed Denver in self-defense after Denver and others yelled "Giants suck." The father told the News-Sentinel that his son alleged Denver hit him over the head with a chair during the fight a few blocks from the stadium. A second suspect was questioned and released by police Friday. Two others were being sought. The stabbing was the latest incident over the years stemming from one of the most passionate rivalries in sports.
