I wouldn’t dismiss TBI / mental health / addiction issues at play, however, if you read the lawsuit docs, this has been going on for a while. It starts to stink of crap is hitting the fan so all of a sudden there is brain cancer… I’m not saying that’s what is going on, but having to forge documents? If he knows he has a ‘glioblastoma’ - then he has had an MRI / CT / biopsy. There would be no need to forge any letter about anything.
Glioblastoma is usually a quick disease - average life expectancy for a healthy 25yr male is about 2yrs. My Mom lasted less than 3 months from symptom onset. There are outliers of course, but the average speaks for itself.
