SAN ANTONIO – The Bexar County Sheriff’s Office spent two hours searching and digging for signs of a woman missing since December 2010. But Salazar said on Thursday that after two hours of work, no evidence was found to help investigators. “Nothing was found today (but) it shows the lengths that law enforcement will go through to make sure on any cold case that we try to find closure,” Salazar said. Salazar said he didn’t know why the man waited this long to report his tip. AdSalazar urged anyone with information about the cold case to call 210-335-6000.
