In an exclusive interview Wednesday night, a man who dated Jodi Arias spoke about her for the first time publicly on HLN. 

Abe Abdelhadi says he dated Arias several times and even spoke to her after ex-boyfriend Travis Alexander's death.

Arias' attorneys have been arguing during her murder trial that she killed Alexander in self-defense, even though Arias has given authorities several stories about Alexander’s death. After Alexander’s body was found in June of 2008 at his Mesa, Arizona home, Arias told police she was not involved in his killing. She later told investigators that she witnessed two intruders break in and kill him. Eventually, her lawyers said she killed Alexander in self-defense.

“When you heard that Travis died, did you for one second at all think she had anything to do with it?” Dr. Drew asked Abdelhadi.

He replied, “Absolutely … [after his death], my phone was blowing up with texts [and] I told a buddy …I know who did it.”
