Sacramento bounty hunter Leonard Padilla says convicted serial killer Wesley Shermantine is endorsing him in this year's mayoral race.

"When you have a guy on death row endorsing you, you have to be somewhat proud of that," Padilla told FOX40.

Shermantine makes up one half of the “Speed Freak Killers,” said to be responsible for the murder of as many as 15 people in the 1980s and 90s. Shermantine’s partner was Loren Herzog, who committed suicide in January.

While most people running for office would try to avoid such an endorsement, Padilla is embracing it.

“If I go out here to the unions; if I go to the fireman and ask for their endorsement, they are going to want something in return. This man can't ask for anything in return," said Padilla.

Padilla has sent Shermantine thousands of dollars to Shermantine for information on victims’ bodies hidden throughout northern California. He says Shermantine’s endorsement won’t hurt his campaign.

"I don't think it will have any backlash because there is nothing about the man that is a secret. He's up there because he killed people. He's giving up bodies, he's doing everything he can to absolve himself of further blame," Padilla told FOX40.

Padilla is running against incumbent Mayor Kevin Johnson, retired insurance agent Richard Jones and Jonathan Rewers, Sacramento’s Parks and Recreation Commission Chairman.

"As long as the arena thing is hanging around the mayor’s neck, I've got a real good chance," said Padilla, referencing the failed deal to build a new sports and entertainment complex in downtown Sacramento. Padilla says if he’s elected, he would appoint Johnson to head an arena committee.
