On October 27, 2015, Alfonso Lopez, 34, was shot and killed at his Fort Worth, Texas, residence after an altercation that began when a group at the home asked another group to leave. The visitors refused, the dispute escalated, and witnesses say 31-year-old Cameron Cummins allegedly produced a handgun and fatally shot Lopez and another person. Witnesses reported that Cummins was asked repeatedly to leave and that he pursued Lopez and his companion before opening fire. Cummins left the scene and was later apprehended and charged with two counts of capital murder.

The case description notes the presence of alcohol and multiple witnesses, and it mentions conflicting statements that complicate reconstructing the sequence of events. What did anyone who was at the residence that night see or hear that could clarify what led to the shooting?
