Police were asking the public’s help late Thursday in finding a missing 78-year-old Cambridge man.
Update on Sept. 3, 2021: The missing man was found by Boston police early Friday on Beacon Street and was taken to a local hospital for an evaluation.
John Julian, who has dementia. has not been seen since going to an eye appointment in Kenmore Square at approximately 11:55 a.m., police said in an email a little less than 12 hours later. He was last seen wearing a blue puffy jacket and is believed to be walking.
Boston Police and other regional agencies have been notified, police said, but anyone with information on Julian is asked to call (617) 349-3300.
Bono would like to know why someone with dementia is apparently being allowed to go to an appointment in a far off land (i.e., Boston) without a companion, friend or escort of some sort. In addition to Mr. Julian’s very unfortunate circumstances (and we hope he is swiftly located) there seem to be others who evidently have a sleeping disorder.
