On the evening of November 23, 2013, a shooter entered a home on North New Haven Avenue in north Tulsa and opened fire on a group gathered in a converted garage. Four people died: Melissa Lynn Dake, 35; her husband Charlie Dean Dake Jr; Glenda Ellen Harper, 54; and Tammy Brunson, 46. Two victims were pronounced dead at the scene and two, including Melissa, died later at a hospital. A fifth person was wounded and survived. Several children present were physically unharmed.

The assailant reportedly entered through a back door. Investigators have looked at numerous leads and considered a possible drug-related motive because of prior drug arrests tied to the residence. The sole surviving shooting victim has cooperated with detectives, though authorities say substance abuse issues may have complicated the information gathered. No suspects or arrests have been publicly identified and the investigation remains active.

Does anyone have information about that house, people who were there that night, or events in north Tulsa around November 2013 that could help investigators?
