Homicide detectives have now charged 19-year-old Sydear Green with the double homicide and double shooting outside a party that was promoted on social media.


As for the motive, "He was angry for getting kicked out--they did a very good-- several week investigation lead us to him," Philadelphia Homicide Captain Jack Ryan said.

Green lives right around the corner on Norris Street. He has no prior record.

Captain Ryan says police are making progress in Duignam's murder. His apartment was ransacked and he was robbed. Police say there was a violent struggle and no signs of forced entry. This was not random.

"We're still looking at a number of different avenues. We have two or three different avenues that they're investigating at this point," Philadelphia Homicide Captain Jack Ryan said.

Captain Ryan noted that the party was promoted on social media. He says anyone attending these open invitation parties should be careful.
