Abe Abdelhadi alleged on Pinsky's HLN show he was introduced to Arias by a friend they had in common.
He said, “…we got into each other`s cars. She told me she liked my energy, that kind of thing… she kind of came off a little flighty. But regardless, she was cute.”
Abdelhadi continued, saying the two exchanged phone numbers and eventually when they saw each other at business events, they would sit next to each other and go out to lunch.

“And then we actually had a dinner date… we finally went out... December of 2006… We went to dinner in Pasadena. We walked around. We went to Barnes & Noble. We ended up in the spiritual books section, philosophy section. She asked me about my religious background… She told me she was dabbling in Mormonism,” he said.
He claimed the two did not have sex, but said he “made a little reach to find out… if she was wearing thong panties or not.”
Abdelhadi said a few days later she called him saying she felt guilty they had gone out because she was getting back together with her ex-boyfriend--presumably referring to Alexander.
Abdelhadi said he stayed in contact with her and then eventually heard about Alexander’s death.
When asked if he initially thought Arias had anything to do with the killing, he said, “Absolutely…There`s no way she didn`t do it. It was premeditated…”
Arias, 32, is accused of murdering Alexander, 30, in 2008, by shooting him in the head with a gun police believe she stole from her grandmother, slashing his throat, and stabbing him 27 times. After police recovered a camera memory card with images including Arias dragging Alexander’s lifeless body along the floor, she admitted to killing him, saying it was in self-defense.
