I can't be positive about the ID on these but I took a picture using google lens and it identified them as Bittersweet.
This dead tree sits just off of my property line. The property belongs to the doctors office behind me. The people who mow for them mow around all the branches that have fallen off of this tree and the weeds are getting quite high around this tree. There are lots of these red berries around the tree so I went out to take a picture of them.
I could complain about this but a couple years ago I mentioned it to someone at the borough office and they told me to contact the doctors office. I even went as far as contacting the doctors office and they said they would look into it. The tree still stands, the weeds still grow. I'm done with it.
