Hi Sweetluv,
Good questions. There are certain characteristics that couldn't be disguised, the physical stature and race. This was a middle-aged white male, under six foot, and about 160 pounds. That is positively not Paradiso who was 6'2" and more than 200 pounds. That's where I start.
You have to look at who had this knowledge and withheld this lead, the police and the Websters. That is verified in records.
Everything points to premeditation. If someone is planning something nefarious, it is a certainty they would not want someone to identify them. No one focused on the driver of the blue car, but the bearded man would be observed. The man had a suitcase. He was travelling. That's the first advantage. He was probably not on home turf.
Joan knew and trusted the man. She acknowledged him to the cabbie. When the man exchanged words over his heavy suitcase, he did not want to take that cab. He was responsible for shifting Joan to a different vehicle. He represented some authority to Joan because she switched cars without any disturbance.
The description of the man and his demeanor is a pretty close fit to George Webster. George suppressed the lead. The only variance is the beard. George was clean shaven. The dress, glasses, and disheveled hair fit the description. George was travelling at some point that weekend. Eleanor and Anne uncharacteristically went with George to drive Joan to Newark Airport. The logical explanation was for them to drive home. Eleanor didn't drive after dark, Anne would have driven if George was no longer in the car for the return trip.
If someone else Joan knew approached her in a disguise, I would think it would have taken Joan aback. It would me. But she would not challenge her father. Remember, George and Eleanor had an intelligence background. In the 1970s, ITT was involved in some covert activities involving political outcomes in Chile. It was George's division and he was the director of budget and planning for the defense group, the DOD. He would have been in the thick of it. If you have those kind of activities in your history, presenting yourself with a different look does not seem unreasonable. Joan would understand that. She was the only child still at home during some of ITT's activity. It later came under the microscope under the Church Senate hearings.
I don't think ITT's involvements would be motive to murder Joan. I'm sure George and Eleanor did not want their image tarnished by any connection to outcomes in Chile. But time had passed and ITT's involvement was public, albeit overshadowed by Watergate. A disguise is a real possibility.
When remains surfaced in Hamilton, MA, George said everything pointed to Joan being dumped at sea. He didn't think the remains were Joan. She was positively identified by dentals. At that point, George and Eleanor couldn't avoid that fact, but Joan was not found anywhere near Boston Harbor. During a media interview on May 4, 1990, George said they still believed Paradiso was guilty. He refused to answer why they still believed that.
When pathologists were done with the remains, George had Joan cremated. In MA, that was a violation of the law to cremate a body if there is still some legal questions. This was an unsolved homicide. George did it anyway. I knew she was cremated at the time, but I did not know what the law was until I dug into the case. The only people present for the internment were George, Eleanor, Steve, myself, and Bucky, the choir director from their church. Anne was a no show.
That August in Nantucket, Anne's husband and I both questioned the premise the family represented. I still did not know about the boat, and thought the Iannuzzi case was a legitimate prosecution. I had no idea about the suppressed lead and the composite. Eleanor told me too much time had passed to figure out what happened. She told my brother-in-law that Paradiso's girlfriend had Joan's ring. That was false. We didn't hear the same thing and unfortunately did not discuss it to learn the discrepancies.
Before Joan's remains surfaced, there were several efforts to get Bond to testify against Paradiso in Joan's case. Bond was burned by promises authorities made during the Iannuzzi case so he would not cooperate. According to Bond, Palombo corresponded with him up to the time of Joan's recovery and told him not to change his story. After finding Joan, efforts to prosecute Paradiso for Joan's murder abruptly stopped.
In 2005, Burke said the Websters visited him and "wanted to know everything about Joan's killer." Burke announced his book in 2006 with the Websters public support and cooperation. In my opinion, loving parents don't endorse a false published narrative about their daughter's brutal murder. Joan's murder has something to do with Webster secrets. I am the one who found the distressing letter and sought help. I became a risk to the family image. Burke's book and the letter were the catalysts to dig into Joan's case.
