Stanley wrote last week: ‘Just found out my little TV Sis’, DAWN LYN (Dodie), is in a COMA and fighting for her life. She had surgery recently to remove a brain tumor. 

‘Please pray for her to have a swift and full recovery. I took Dawn out to lunch a couple of months ago. We had a great time reminiscing about our MTS days. Dawn is one of the nicest human beings I have ever known. 

‘Thoughts and prayers also go out to her husband, John, at this time. This is devastating news!” 

Tina wrote: ‘My heartfelt prayers go out to my “My Three Sons” sweet “lil’ sis”, Dawn Lyn (Dodie) and her husband John. Dawn is fighting for her life after undergoing brain surgery.’

Lyn’s brother, actor and musician Leif Garrett, 60, told the publication: ‘My sister, Dawn, never wanted anyone to know about the surgery. 

‘Since it has been leaked on social media, I would really appreciate everyone’s understanding that it has already been a difficult time having lost both of our parents and a cousin recently.’

‘Please just keep my sister in your thoughts and prayers and respect our family’s privacy. Thank you.’
