“I heard some shouting but only from one person. I could hear him yelling but couldn’t hear what he was saying,” said neighbor Angela Thompson.

Thompson said she never heard the gunshot but found Spencer, 44, and called 911.

“I walk down there and he was laying there and there was blood all around his head and I saw it was Eric Spencer because he used to live here,” said Thompson.

Thompson said it’s concerning because there are a lot of questions that remain after his death.

“There’s a community of people on both sides of it, I know both sides of it so I’m kind of neutral on the situation but it’s stirred up the community up here. We all have questions but we’re not getting answers,” said Amanda Hunt, friend of both the victim and gunman.
