Wonder if they knew each other. They are both way over 65.
My sympathies are with the home owner, just would like to know more.
From the article: “Stevens’ family says he has a history of dementia and Alzheimer’s, which may be a factor in the case. His sister-in-law lives next door to Foster.”
Stevens (the intruder) is the brother-in-law of Foster’s next door neighbor. It sounds to me like he went to visit the SIL, but his confusion resulted in his eventual death.
