No they haven’t. Apart from their original police contact in 1969, apart from one interview, they have remained relatively anonymous, and it will likely remain that way. Here is their expanded testimony:
"As both Robbins kids were the oldest, their statements were the given the most weight. Also they were the least traumatized by the event. One of the kids (not sure which) noticed a cab parked outside (in that now famous spot) with the interior lights on. So when Lindsey told me that the light inside the car was like a spotlight, it was so bright.
The first kid at the window said the driver looked "sick, or something". Lindsey and Rebecca went to the window and saw the driver laying across the front seat, head toward the passenger door. His head was in the lap of another man (passenger). Rebecca saw blood and said out loud, "he’s stabbing that man." She was seeing blood on the victim and saw the glint of a knife, so she assumed a stabbing was taking place. (No shots were heard by anyone). We know now that Zodiac was cutting off a large piece of Stine’s shirt with the knife.
At this time, Lindsey went downstairs to get a better look at what was happening, while one of the kids upstairs called the police. Downstairs, the lights were off, so Lindsey knew he could not be seen from the outside. He got close to the window and watched his actions. He was shortly joined by Rebecca. They both watched and observed in silence as Zodiac pushed the driver to an upright position behind the steering wheel, exited the car and walked around the rear of the car and opened the driver’s door. Stine had fallen over onto the seat and Zodiac pulled him back up into the seated position and had some difficulty keeping him upright. Once upright, he was seen to have a rag, or something like a handkerchief and began to wipe down the door area and leaning over the driver, part of the dashboard. When he was finished, Zodiac calmly walked to Cherry St. and walked north.
Not many know this, but Lindsey (being 16. feeling immortal, and believing the suspect to be armed with only a knife) ran out of his door to see where Zodiac was going. He ran to the corner of Cherry and watched as Zodiac continued his casual pace right up to the corner of Jackson & Cherry." ​

Thanks for your response, Richard! I admire what they did as kids back in ’69 and completely understand them wanting to stay private ever since. Thanks again for answering my question and providing the additional info

Richard, wouldn’t you think they’ve run the key suspects by them over the years though?

They may have, but the teenagers haven’t since stated, or its been issued for public consumption, is what I was trying to say.

Richard this is a basic question, but at what point was it public knowledge that the Stine murder was the work of the Zodiac? Did the police have suspicions right away, or did they treat it as a random event until the letter came in?

The police, from what we know, took it as a ‘routine’ taxicab murder. That all changed on October 13th 1969, with the Stine letter: "This is the Zodiac speaking. I am the murderer of the taxi driver over by Washington St + Maple St last night, to prove this here is a blood stained piece of his shirt."
On October 15th 1969 the San Francisco ran an article entitled ‘The Boastful Slayer’ revealing the Zodiac connection.

Does anyone know (and sorry if I missed a discussion about it on this board) if Lindsay Robbins (or the other kids) have ever indicated that any of the well known suspects look like the man they saw outside the cab that night? Bryan Hartnell has stated he would recognize Z’s voice if he ever heard it again. So what about the kids?…seems like they would be able to tell if any of the suspects could be Z or not.

Mike Rodelli’s book Hunt for Zodiac features extensive quotes from Lindsey Robbins, from interviews with retired Vallejo detective Jim Dean in 2003. Robbins said that Kjell Qvale’s resemblance to Zodiac was "extraordinary," among other things.

Is Qvale the focus of that book?

Just read the passage. One thing mentioned is Graysmith not interviewing Robbins or Foulke. What was the explanation for this?

Yes, Qvale is the focus, since he’s Rodelli’s suspect. (I meant THE HUNT FOR ZODIAC, by the way; HUNTING THE ZODIAC is the old amateur Zodiac hunters documentary.)

The case against KQ aside, it’s worthwhile for the Fouke and Robbins material. Plus, Vince Repetto had some pretty eye-opening things to say about the Stine case. I’m sure there’s more, that’s just off the top of my head at 11PM.

As for Graysmith, I’d agree with Rodelli that he likely just wasn’t interested in information that conflicted with Allen being Z. SFPD never showed Robbins a picture of Allen, either (Bawart did, many years later). I guess it’s one of those eternal debates. It’s been established there was no fog that night, so why did Graysmith feel compelled to manufacture one? Was a fog mentioned in any of the newspaper reports at the time? Bad journalism, personal agenda, or was he just overly beholden to Toschi?

How closely did Qvale’s face match Ross Sullivan’s?

Hi,

It’s a miracle! Someone is finally discussing my book!

Xcaliber, the case against Qvale runs MUCH, MUCH deeper than just a resemblance to the sketch. If you read my book, you will see.

As for Lindsey, yes, that was one of the most memorable days of my life. It’s a pretty amazing story.

As for Vince Repetto, he had an interesting observation about the corner of Washington and Maple that shows that someone living in the North Bay or even in downtown SF would have little chance of being familiar with that intersection.

The interview Lindsey gave is the only one I know of that he ever gave to any civilian researcher. I do not know what he may have said to Fincher when he allegedly had dinner with him, but I am guessing it was not as in depth as what he told Jim in 2003. If you want to know what he thinks about the night of the Stine murder and of KQ, I have extensive passages that discuss his story.

As for Graysmith, he managed to avoid BOTH the Robbins kids and Fouke. Fouke wanted to be interviewed but Graysmith wrote two books and never spoke to him. You figure out his motive.

Both Fouke and Linsdey completely laughed at the possibility that it was anyone as big as Allen that they saw that night.

Mike

Very interesting, and from the passages I’ve read it seems that old-fashioned investigative journalism is the foundation of the book.

Hi,

Well, I am not a "journalist" but I did a lot of research.
