News stations have learned Casey Anthony might have made up the name of Caylee’s so-called nanny, Zenaida Gonzalez, from former classmates’ names and the street name for a drug. Investigators are now looking into it because of  questions.

Casey Anthony said she used to call Zenaida Gonzalez “Zanny,” which reporters found out is also the street name for the anti-anxiety drug Xanax. Word is that investigators have asked at least one of her friends questions about Casey and Xanax during a lie detector test.

Casey Anthony had apparently asked her ex-fiancé Jesse Grund about Xanax while they were instant-messaging during the time they were engaged. Grund was asked the questions when he was hooked up to a polygraph by the FBI.

Xanax goes by the name “Zanny” on the street, which has some wondering if “Zanny the nanny” was a reference to the drug and not the nickname Casey says she used for the mysterious nanny, Zenaida Gonzalez.

A girl named Zenaida was in Casey’s homeroom at Colonial High School before Casey dropped out. She had a different last name, not Gonzalez, but there were seven students in her class whose last name is Gonzalez.

The names Casey has made up as her friends who introduced her to Zenaida also show up in her Colonial High School classmates roster. She named a Raquel Ferrell, who investigators say does not exist, but there was a Raquel Rosa in her class. Casey also named Jennifer Rosa as a friend whom investigators can’t find. She had a classmate named James Ferrell and the name Jennifer shows up close by.

Investigators are now checking into it to find out whether it’s more than just a series of coincidences.

George Anthony lashed out at reporters Wednesday, one day after his daughter, Casey Anthony, was released from jail on home confinement for the third time. George and Cindy Anthony could get some relief from protesters in their neighborhood as early as next week.

For the first time in several days, George Anthony spoke out. He seemed to have pent up anger against both protesters and the media.

“You are destroying my family, all of you. I wish you would get the hell out of here,” he said. “I feel sorry for all of you. Some day you’re going to have a judgment day, all of you.”

Protesters have started to show up again now that Casey is home.
