VALLEJO, Calif. (KGO) -- While the Vallejo Police Department claimed a kidnapping in March was a hoax, the Alameda County Sheriff's Office was working a case that would prove it was real. And now Sheriff Greg Ahern is calling a Dublin homeowner who fought off the suspect in another home invasion a hero.[br /][br /][b][url HREF="http://abc7ne.ws/1I1QgfA" TARGET="" REL=""]VIDEO: Vallejo police address kidnapping they'd called a hoax[/url][/b][br /][post ID="851618" /][br /][br /]The sheriff believes the suspect, 38-year-old Matthew Muller of Orangevale, Calif., may be responsible for even more attacks. And just to be sure, his investigators are looking at similar unsolved crimes.[br /][br /]"In 35 years, this is about as bizarre of an investigation that I've been involved with," Ahern said.[br /][br /]On Tuesday, Ahern commended his deputies on cracking the bizarre case and proving the Vallejo home invasion and kidnapping was not a hoax.[br /][br /]"This certainly, however, ranks at the top of the strange scale," said Chronicle reporter Henry Lee.[br /][br /][b][url HREF="http://abc7ne.ws/1Gk6MSL" TARGET="" REL=""]VIDEO: Vallejo 'Gone Girl' kidnapping suspect tied to other home invasions[/url][/b][br /][Ads /][br /][post ID="850886" /][br /][br /]Lee also says it's one of the most bizarre stories he's ever covered.[br /][br /]It was the work of a sheriff's investigation into another home invasion in Dublin that led authorities to Muller, the Harvard-trained former lawyer who's charged in that kidnapping of Denise Huskins.[br /][br /]The sheriff also gave credit to the Dublin homeowner who fought Muller when he broke into his house.[br /][br /]"Making that decision spontaneously probably saved them all from being victimized further," Ahern said.[br /][br /]Lee even became an unwitting participant when he began [url HREF="http://abc7ne.ws/1HtqnUv" TARGET="" REL=""]receiving emails[/url] from someone claiming to be the kidnapper, containing details of the attack.[br /][br /]The first one, the day after the incident, said, "Victim 'F' (Denise Huskins) will be returned safely tomorrow."[br /][br /][b][url HREF="http://abc7ne.ws/1HtqnUv" TARGET="" REL=""]VIDEO: Email sent by alleged kidnappers of Vallejo woman threatens police[/url][/b][br /][post ID="597834" /][br /][br /]The four emails to Lee said there were several kidnappers involved.
