A 35-year-old man was seriously injured Saturday morning when he was shot in east Modesto, police said. The Modesto man was listed in critical but stable condition Saturday evening at a local hospital, said Modesto police Lt. Ron Cloward. About 9:10 a.m., the injured man flagged down a city bus for help in the area of Creekwood Drive, north of Yosemite Boulevard and about a block west of Claus Road. The bus driver called police. Cloward said the officers followed a blood trail to the 500 block of Waddell Way, where police believe the shooting occurred. The victim, however, was not cooperative with investigating officers, so police did not have a description of anyone involved or any other details about what might have led to the shooting, Cloward said. Police ask anyone with information about this shooting to call Crime Stoppers at 521-4636. Tipsters also can e-mail tips through the Crime Stoppers Web site, www.stancrimetips.org, or text tips to CRIMES (274637) by typing "Tip704" and a message.
