Exonerated murder mom CASEY ANTHONY changes hideouts to ditch subpoena but she’s been found—AGAIN!

Casey had beenhiding out in the South Florida area but moved last week because she began to fear for her safety and is once again on the move.

Anthony has been in hiding in Florida since she was acquitted of murdering her two-year-old daughter, Caylee, but has recently been making forays back out in to the public, virtually unrecognizable due to the amount of weight she has gained.

Anthony is on probation for one year after pleading guilty to passing bad checks and is required to live in Florida. Once Casey's probation ends she plans on ditching the sunshine state for Costa Rica.

"Casey absolutely flipped out when she found out that private investigators hired by Zenaida Gonzalez (who is suing Anthony for defamation), discovered where she was," a source told RadarOnline.com.

"The private investigators were attempting to serve Casey with a subpoena to appear at the trial, which is expected to begin in January. Casey had been venturing out at night and the investigators had been tipped off by people that had seen her. Casey is a smart girl and quickly determined that she had been found and refused to leave the house or accept service of the subpoena. The P.I.s weren't stalking her or doing any surveillance, they just wanted to serve her and move on.

"Casey was extremely upset that she had been found because she had settled into a routine and felt safe in South Florida.

Casey's lawyer advised her that she needed to move though and they worked together over the past two weeks to move yet again. Casey is hopeful that this will be the final move before her probation ends, at which time, she doesn't have to stay in Florida."

Zenaida Gonzalez, is currently embroiled in a legal battle with Casey, suing her for defamation, after the notorious “Tot Mom” told police investigators that a woman with a similar name to Gonzalez's had kidnapped Caylee.
