Police said Feldheim went to a home in Cockeysville around 7 a.m. Dec. 14 and told the 87-year-old man who lived there that there was something wrong with his well, and it needed to be checked.
When the man went to close the door, Feldheim grabbed his arm, pulled him to the ground, got on top of him and started to put his arm around his neck.
