Rene Yanez, 21, disappeared after a nighttime ride from Darlington Stables in San Gabriel, California, on February 10, 1993. Around 9:30 p.m. he left on his horse La Mora with his white pit bull terrier Queen for a familiar route along the San Gabriel River. The following day both animals returned to the stables without Rene; the saddle was askew and the horse’s blanket was wet.

Searchers tracked Rene’s scent to a spot between the Whittier Narrows Dam and San Gabriel Boulevard. Divers, search-and-rescue teams and family members conducted extensive searches but no sign of Rene was found. Authorities suspect he may have tried to ford the river and drowned, though his body was never recovered. He was an experienced rider who competed in rodeos and lived in Rosemead with his wife and young son.

Does anyone who rode the San Gabriel River trails in 1993 or knew Rene have information that could help explain what happened that night?
