Nearly a month after Joseph Mahoney and Josh Norris, both 17, of Deerfield were charged as adults in a Highland Park home invasion August 2, their relationship with one of the residents of the house as well as the source of the gun used has become known.

On Friday, Deerfield Police told Patch Norris and Mahoney gained access to a Deerfield home through a ruse August 1, the right before the Highland Park burglary, to obtain the shot gun Mahoney used when he allegedly broke into the home on Parkside in Highland Park.

On Tuesday, Mahoney’s attorney, Chris Cronson, told Patch one of the residents of the Highland Park home, Jacob Lynn, was a source of marijuana supply to Norris and Mahoney.

A few days before that on August 17, Lynn was charged with possession of marijuana with intent to sell by Highland Park Police. The burglary investigation helped lead to the arrest.
