Aside from a possible gang-related shooting at the Belmont Park parking lot Sunday, where a car was struck several times, police officials reported the Memorial Day weekend passed without a significant incident. No one was injured in the May 24 shooting. Police are continuing to investigate and search for witnesses, said Lt. Jorge Duran, a gang unit investigator with the San Diego Police Department. “We are hoping somebody in the community may have seen or heard something,” Duran said. “Tying to find folks to cooperate with the gang unit is a challenge.” Beach-area patrols arrested 13 suspected drunken drivers during a DUI checkpoint along Garnet Avenue on Friday, May 22. Other drivers were arrested for driving without licenses and other offenses. Funding for DUI checkpoints comes from an estimated $1 million grant from the California Office of Traffic Safety, McCullough said, and pays for overtime. Police handed out about 122 misdemeanor alcohol citations in Mission, Ocean and Pacific beaches, according to Northern Division Capt. Shelley Zimmerman. An increase in arrests means police are doing their job, said Police Officer Mark McCullough. “It’s not that there are more drunk drivers, we just have more enforcement,” McCullough said. “If we’re not seeing an increase in alcohol-related vehicle collisions then we know that we’re holding the line.” He said no major collisions were reported. The second Memorial Day weekend since the start of a beach alcohol ban – a temporary ban last summer and now a permanent ban approved by voters late last year – lured about 750,000 sandal-clad tourists and families over the three-day weekend. “Did the alcohol ban play a role? …Yes, without question that the atmosphere is very relaxing, very welcoming, even though we had 500,000 more people compared to last year,” Zimmerman said. Lifeguards also had their hands full over the holiday weekend. San Diego Lifeguard Lt. Andy Lerum said strong currents and throngs of people made for a lot of rescue activity. Lifeguards reported 219 water rescues and 229 calls for medical attention over the three-day weekend. “Overall, it was pretty busy but nothing spectacular,” Lerum said. “There were no major incidents to report.”
