(CNN) -- A California bounty hunter says he will sue Casey Anthony and her defense attorney Jose Baez for misleading him when he helped search for her young daughter Caylee. 

Leonard Padilla said he is seeking $200,000. 

Padilla said Anthony's attorney allowed him to fly to Florida in 2008 and help search for Anthony's then-missing 2-year-old daughter. 

Anthony left jail Sunday after being acquitted of murder charges in connection with the death of her daughter. 

Padilla says when he heard Baez's opening statement during Anthony's murder trial he felt conned. 

"It turns out she knew where the child was all along," Padilla said. "They misled me, and it is definitely fraud." 

At one point during the highly-publicized search for Caylee, Padilla offered a $25,000 reward for the girl's return. 

He also says he spent $50,000 to bond out Anthony when she was initially jailed. He said he also brought in people to help provide security. 

He said he talked to Anthony on many occasions during that time and that she never said she knew where Caylee was. 

"She told me the babysitter stole the baby," Padilla said. "They were both feeding us that line. And now we know it was never true. We lost a lot of money." 

Padilla says it may take a few weeks to get his lawsuit together. 

Johnny Griffin, a California legal expert, told CNN affiliate KCRA that Padilla's lawsuit may have legal merit. But he may need to do some work to prove his case, Griffin said.
