Dangerous Liaisons

How Far Would You Go For Love?

(CBS)  Sandee had been shot eight times at point blank range while she sat defenseless in her car. "There was a significant amount of glass," says lead investigator Paul Andrews, describing the crime scene. "Absolutely a tremendous amount of blood."

"And multiple shell casings that you could see on the floor of the garage and just outside the garage," says Andrews. "Somebody had it out for her, this wasn’t a random act."

With Sandee’s death, the assault charges against Tracey were dropped but his troubles were far from over: he was now the prime suspect in her murder.

Almost from the start, police were convinced that Tracey was behind Sandee's murder. The trouble was, at the time of the murder, he was at home, eating pizza.

"We spoke to the pizza deliveryman, we described Tracey Humphrey to him, and he remembered going there," says Det. Scott Golczewski.

Shortly after the murder, Golczewski went to the gym where Tracey worked. When Tracey refused to speak with him, Golczewski decided to stop by Tracey’s apartment and talk with his new wife, Ashley.

"She was very nervous, very scared," he recalls. "She almost threw up twice when I was interviewing her."

However, it wasn’t long before Tracey showed up and the interview ended.

Asked what he thought when he left the couple's apartment, Gokzewski says, "I said 'She’s definitely involved, she definitely knows something.'”

The trail to finding out just what Ashley knew began when Golczewski and his partner, Paul Andrews, got a tip from the fire department who had heard about the case.

The fire department told homicide detectives they found Ashley’s car in flames in Tampa a month before the murder. Ashley had reported it stolen. Investigators suspected arson and turned over a background check they had run on her to Andrews and Golczewski, who noticed some unusual purchases.

"She had purchased a couple of computer software programs that would enable her to look for somebody. One of them actually was a search, that she paid for on her credit card, for Sandra Rozzo," says Det. Andrews.

Another break came when they spoke with the co-signer of Ashley’s car loan, David Abernathy, her mother’s boyfriend.

"As we were leaving, I just asked him if he has any firearms. And he said he used to," Golczewski recalls.

Abernathy told them he no longer had a gun because he had loaned it to Ashley. Andrews says it was "very big" break in the investigation.

It was explosive evidence. The shell casings from Abernathy’s gun - a Ruger .22 caliber - matched the type found in Sandee’s garage on the night of the murder.

Ashley’s cell phone records on the day of the murder sealed their case.

"Ashley's cell phone is not only bouncing off of the antenna near Miss Rozzo's place of business, but then crossing over into Pinellas County, and then a few minutes after the homicide, bouncing off of a cell phone tower in Pinellas Park," says Golczewski.

This information was crucial - it placed Ashley in Sandee’s neighborhood at the exact time of the murder.

Now with a mountain of evidence against her, police arrested Ashley for the murder of Sandee Rozzo.

During the police interrogation, which was recorded, Ashley told police she didn't know Sandee.

"I told her in the interview, 'There is no more going to the malls, there is no more going to the gym working out. This is it for you,'" recalls Det. Golczewski.

At one point, Ashley told Golczewski, "Get my attorney."

Asked what she meant, she replied, "I mean bring him here."

But her tough talk didn't last long. After three weeks behind bars, Ashley cracked, confessing to gunning down Sandee. She told police she did because she was afraid of losing Tracey.
