Searching for Answers, Casey Anthony's Father Bought Gun

Casey Anthony's father, George Anthony, on the witness stand again Wednesday, testified that he bought a gun in August 2008, planning to use it to force his daughter's friends, by gunpoint, to tell him what happened to his then-missing granddaughter, Reuters reported.

George, however, said he never used the gun he bought.

I wanted to get answers from people that I believed were involved with my granddaughter (being) missing, he said.

At the time of the gun purchase, Casey Anthony was under house arrest for lying to detectives during their investigation into Caylee's disappearance; within hours, someone from the jail would arrive at the Anthony home to confiscate the weapon, as it violated the terms of Casey's house arrest.

Casey Anthony is accused of murdering her 2-year-old daughter and could face the death penalty if convicted. She has pleaded not guilty. The defense claims Caylee accidentally drowned in the family pool in the summer of 2008 and George Anthony helped dispose of the body.

George denies those allegations, saying he continued to believe Casey's account of a kidnapping, even after Caylee's remains were found in woods near their home on December 11, 2008.

On Tuesday, George also revealed that he attempted suicide to be reunited with his dead granddaughter.

A tearful George Anthony told jurors he still battles with suicidal thoughts and that on Jan. 22, 2009, he took a mixture of medications and beer to try to end his life.

My emotional state even through today is very hard to accept that I don't have a granddaughter any more. But for that particular day [Jan. 22, 2009] ... it just felt like the right time to go and be with Caylee, he said.

George Anthony also described writing an eight-page suicide note.

I wrote this specific letter to my wife Cindy to tell her how I felt and how I didn't want to be in this world anymore, he said. At another point, when the jury was out of the room, George Anthony said, It just felt like the right time to go and be with Caylee. I believed I had failed her, he told jurors in the sixth week of the highly publicized first-degree murder trial in Orlando.
