CA CA- Lucien Vink, 51, last seen carrying a backpack, San Clemente near Camino Forestal/Calle Precipicio, left note, 6 July, 2025, *'Critical.'*

[angelainwi]

Also, something that stood out to me is that the wife claims she thinks he went through a “glucose psychosis”. This is very rare and also symptoms may include:

• Confusion
• Hallucinations (visual or auditory)
• Paranoia
• Delusions
• Disorganized thinking
• Aggression or inappropriate behavior
• In rare cases: full psychotic breaks

Idk…Lucien could have experienced altered mental status from high blood sugar, but the details (a coherent note, purposeful walking, middle-of-the-night timing) suggest either a partially lucid state—or something else entirely.

What do you guys think? Am I crazy?! I feel like there is more to this.

That is scary! Never heard of it.

It sounds like he had an insulin pump and a CGM (continuous glucose monitor.) I’d be surprised if his blood sugar got so far out of range that he experienced psychosis. Mild confusion possibly, but psychosis would be very rare. In a non-compliant diabetic, blood sugar extreme swings are more common. Since he had an insulin pump, his blood sugar was likely well controlled. Now, since his blood sugar supplies were left at home per report, his blood sugars may be very out of control. But they were likely well controlled up until he left the home.
Unfortunately, this sounds like he may have planned to take his own life. Statistically, the majority of people who completed suicide gave no signs that they were going to harm themselves. The note and leaving important belongings at home are suspicious for suicide. I hope and pray that I am wrong.
This is just my opinion as an RN who worked with psychiatric patients for many years.

Does anyone think the wife’s timeline is a little weird? I don’t know if I am looking into to it too much but originally OCSD’s bulletin indicated the note left by Lucien stated something about self harm. However, the wife’s interview with NBC News, she states that she read the note and thought “that’s bizarre” and then she decided to take a shower?! Idk what do you guys think? I see some inconsistencies.

You are not crazy. It definitely deserves looking at hospital or physician visits as well as the device readings to verify this extremely rare condition.

I agree that many "happy" appearing individuals do commit suicide. You can never really determine the pain and hopelessness an individual may be experiencing. It is really important to determine ALL the possibilities that could have occurred in this case and systematically eliminate those with evidence to exclude them.

What I find odd is he took a back pack?

Exactly! Why would he leave his house so late at night and potentially get a car ride?

 

[Iamlost30]

Here is his LinkedIn page. Very acomplished individual. (looks like he got his undergraduate and graduate degrees in the Netherlands). Although I know it' a lot more common for people who grow up abroad, his ability to speak four languages is impressive to me personally.
https://www.linkedin.com/in/solucien. His being without his insulin is worrisome. My older brother was diabetic and he would have some issues including behavior changes if his blood sugar was seriously off.

Just because he didn't have his insulin and glucometer on his being, doesn't necessarily mean that he didn't have access to a stand alone glucometer and insulin vials. Not sure if this was the case, but it is a possibility.

No sign of 51-year-old ‘critical’ missing person in San Clemente, California

Lucien Vink walked away from his home on the morning of July 7, 2025. He is a type 1 diabetic and left his glucose monitor and insulin administration device at home.

www.nbcnews.com

''Carly told Dateline she woke up that morning to go to a 6:30 gym class, and Lucien was not in bed, which was totally normal. “He does have type 1 diabetes, and he wears monitoring devices that can beep very loudly sometimes. So if he has high blood sugar, he’ll very commonly sleep on the couch,” she explained.

Carly went downstairs, but Lucien was not on the couch. “I thought, ‘Oh, one of the kids must have woken up while he was still up last night, and he went and fell asleep in one of their rooms,’” she said.''

I try to be neutral as much as possible when determining what is a normal behavioral response to an incident. I am still trying to wrap my head around a person leaving their house with two small children asleep and not verifying that everyone is accountable before leaving the house.

What I find odd is he took a back pack?

I found that odd at first too…
Its unpleasant to consider but looking from a suicide standpoint, maybe he wanted to take some personal/sentimental or even ceremonial items with him? Also, depending on which method he hypothetically chose to complete the task, he may have needed supplies to carry it out. IMO.

 

[GraceG]

Wow this is just sad, he seems to have had a pretty good life. Plus 2 young children. Depression/ mental illness? Wonder if he took out a large life insurance policy recently.

If he did intend to end his life and took out insurance for his family, IMO the last thing he'd do is leave a note, as suicide pretty much nullifies the life insurance payout.

The content of the note would explain a note more, LE indicates it indicated "self harm" yet, the wordage was not such that his wife went into panic mode (which I would have). The actions of leaving the note, organizing (perhaps) and taking a backpack, do sound deliberate to me, so I'd think it unrealted to a "glucose psychosis" as has been suggested.

 

[teeby]

To me the "glucose psychosis" theory sounds like a loved one in denial. People don't want to believe that their loved one could be suicidal and they wouldn't know.

I totally agree. I don’t think he was experiencing “glucose psychosis”.

Great point!

 

[Iamlost30]

I am an RN and I have never seen this in my 34 years of nursing! I am not saying this could not have occurred but if it had, there has to be some sort of documentation on a glucose meter or doctor/ ER visit.

 

[Iamlost30]

Someone just doesn't have "glucose psychosis". This extremely rare condition requires immediate medical attention/ hospitalization.

You can still be lucid and purposeful when experiencing psychosis. I had a client who would write fairly coherent emails to a specific politician when she was in active psychosis. She has no idea why, because he was an elected official in a province she'd never even been to, but she was able to find the contact info for his office, draft long emails and send them.

There's no reason to think that's what's happening here, because it seems pretty obvious (to me anyway) that he's contemplating suicide, but I wanted to note that the details here aren't necessarily inconsistent with psychosis.

We can all remember patients that we took care of and people who we knew experiencing psychosis. My experience as an RN taking care of newly diagnosed insulin dependent individuals presenting with extremely high or low glucose levels ( possibly diabetic psychosis), individuals may exhibit disorganized speech and thought patterns, making it challenging to communicate coherently. The inclusion of really high or really low blood sugar levels make it extremely difficult to physically function let alone feel up to dealing with the effects on mental processing. Long-term insulin dependent individuals may be more equipped to handle extreme fluctuations in blood sugar levels.

I feel horrible for the family and for Lucien. What ever happened to him is tragic and it breaks my heart especially for the children. My hope is that this case can be solved and allow for the family to move on heal.

Not necessarily. My friend’s husband recently killed himself and she got his life insurance payout because the policy was over 2 years old.

I believe glucose psychosis and psychosis present differently

 

[angelainwi]

This is correct, most life insurance companies have a clause for suicide that they will pay out if the suicide is more than 2 years from when the policy was written.
