ORANGE COUNTY, FL -- A disturbing journal entry is among the many pieces of evidence released Wednesday in the Casey Anthony murder case.
Investigators believe the entry, dated June 21st, was made around the time Caylee Anthony was murdered.
Casey wrote, "This is the happiest I have been in a very long time. I hope that my happiness will continue to grow."
She continued, saying she had "no regrets, just a bit worried. I just want for everything to work out okay. I completely trust my own judgment and knew that I made the right decision. I just hope that the end justifies the means. I just want to know what the future will hold for me. I guess I will soon see."
Some 500 pages of discovery information (see the discovery photos) were released by the Orange County State Attorney's Office, including photographs and investigative documents.
Investigators believe Caylee Anthony (photos) was murdered between June 16 and June 27. They believe her body was placed in the trunk of Casey Anthony's car and left there for some time, but was removed before the 27th.
The toddler's remains were found by a county meter reader in December, not far from the Anthony home.
One document indicated that duct tape found on Caylee Anthony's skull matched duct tape found on a gas can at George and Cindy Anthony's house. According to the document the tape "originated from the same source roll." The report mentions "Henkel Consumer Adhesives" as the manufacturer of the duct tape.
Caylee's skull was found near a black plastic bag. Detective Yuri Melich wrote in his report, "I immediately noticed that there appeared to be a piece of silver duct tape across the mouth area of the skull. The tape appeared to have been purposely placed there."
"Evidence on the body suggests that the child's death was notaccidental but an intentional act," Melich wrote on Febraury 5. He added that "there is nothing to suggest that anyone but Casey Anthonyis responsible for the death and disposal of Caylee Anthony."
The documents also list items found near the remains including a Gatorade Cool Blue bottle with unknown liquid and white sediment. A syringe inside a toilet paper roll was found in the bottle. A Winnie the Pooh blanket and children's clothing were found, as well.
Items taken from the Anthony home are also listed, including a red gas can withduct tap attached, garbage bags, a Bissel steam cleaner, Dirt Devilvacuum cleaner, shows from Casey Anthony's closet, a sheet with redheart stickers, and numerous other pieces of evidence.
Casey, who's in the Orange County Jail on first degree murder charges, says she didn't kill her daughter. She told investigators Caylee was kidnapped by a babysitter.
Her trial isn't expected to take place until late this year at the earliest.
