There was evidence of high levels of chloroform in the trunk of Casey's car and sheriff's investigators found that someone on Casey Anthony's computer was researching not where to buy chloroform, but how to make it yourself, which can be done easily.

Eyewitness News legal analyst Bill Sheaffer says, if you were up to no good, there would be an advantage to making it as opposed to buying it.

When you Google "how do you make chloroform," more than a million websites are listed with instructions. On the first one, page one had an explicit warning about chloroform's dangers, calling the chemical extremely dangerous and unpredictable and warning never to allow children to come near chloroform.

FBI lab tests show high levels of chloroform in the trunk of Casey's car, where investigators say Caylee's body had been. And there was a mysterious stain in the trunk along with Caylee's hairs and dirt.

"Another piece of evidence in the circumstantial chain," Sheaffer said.

Sheaffer said it's significant because, if Casey made the chloroform as opposed to buying it, she could have been trying to cover her tracks. Buying it would have generated some sort of record.

"This way certainly, she could argue, 'Alright, I was interested in looking into how to make chloroform, but I never did.' Or, 'That's why you smelled chloroform in the trunk area, because I was experimenting in making it,'" Sheaffer said.

Record or not, the jury would be faced with a compromising question for Casey.

"Why would you need to make chloroform. For what purpose?" Sheaffer questioned.

Last week, the Orange County grand jury heard from the FBI and one of the sheriff's computer investigators and that information is going to be released to the public very soon.

CASEY'S ATTORNEY TO START QUESTIONING WITNESSES

Casey Anthony's defense attorney is going to start questioning his first prosecution witnesses in the case next Thursday. Among those being questioned is an employee at the Amscot on Goldenrod and Highway 50 where Casey abandoned her car in late June, employees from Johnson's Wrecker Service, the company that towed the car from the Amscot, and Casey's ex-boyfriend Tony Lazzaro.

What do they all have in common? They all had access to Casey's car.

OVER $250 DEPOSITED INTO CASEY'S JAIL ACCOUNT

Complete strangers who feel sorry for Casey Anthony are depositing money into her jail account. On Monday, Eyewitness News reported how Casey was lonely in jail with no visitors except her attorney and no money to spend.

Just two days later, she has more than $250. Fifty dollars came from Nola Copeland of California. She's been following Casey's story nationally and, on the phone, she told Eyewitness News she's a good Christian who knows what jail is like and she wanted to make sure Casey could buy the basics like deodorant.

A second woman from Apopka sent Casey $100, but she didn't return calls.

Casey's father and her bail bondsman deposited just over $100 over the last few days.

The jail says inmate accounts cannot hold more than $500. If Casey's account goes above that, the money will be returned to the donor.

FAMILY SETS UP CAYLEE TIP LINE

In spite of the evidence proving otherwise, the Anthony family insists missing toddler Caylee is still alive. A new tip line was up and running Wednesday morning.

Eyewitness News first reported the family's plans to start the new tip line last week, hours after the spokesperson for Casey's attorney admitted on national television that he believes Caylee is dead (read previous report).

The tip line number is: 1-888-231–5618.

CRIMINAL DEFENSE ATTORNEY JOINS CASEY'S DEFENSE TEAM

Casey Anthony's rookie lawyer is getting some help. Jose Baez doesn't have the credentials to try a death penalty case, so he's enlisted the help of a Miami lawyer who's defended some brutal murderers.

Miami criminal defense attorney Terence Lenamon has joined the Casey Anthony defense team. Two of the three high-profile murderers Eyewitness News knows he's defended are on death row. The other is serving five consecutive life sentences.

Terence Lenamon would not talk to Eyewitness News on Tuesday. He's now part of accused killer Casey Anthony's defense team. She could face the death penalty for the murder of her daughter Caylee. Her attorney, Jose Baez, is not qualified to handle death penalty cases, but Lenamon is.

Lenamon is a highly-rated defense attorney. Still, two of three high-profile murderers he's defended in recent years are on Florida's death row.

One of them is known as "The Miami Strangler." Harrel Franklin Braddy, 59 was sent to death row last year for literally feeding little Quatisha Maycock to the alligators in the Everglades after strangling her mother and leaving her for dead. The jury voted 11-1 for death. Braddy had already been convicted of choking a corrections officer. Lenamon had tried to convince the jury the little girl's murder was not intentional, but "a horrible mistake."

Two months ago, a jury voted 8-4 to send another of Lenamon's clients to death row, 31-year-old Wadada Delhall, for murdering a key witness who testified against his brother in a murder case.

One of his high-profile Miami murder clients did escape the death penalty. Cesar Mena, 29, a member of the so-called "Orlando Boys," who raped and killed Ana Maria Angel and stabbed her high school sweetheart, is serving five consecutive life sentences.

Casey's defense attorney keeps insisting Caylee is still alive, even though a grand jury indicted her for premeditated murder after hearing the evidence the FBI and Orange County sheriff's investigators have against her. That evidence includes DNA from the trunk of Casey's car showing Caylee's decomposing body had been in it.

If Caylee's body is not found before trial, it's unlikely Baez will need help from a death penalty-qualified attorney, because without a body there probably would be no push for the death penalty.
