Glenda Ellen Harper, 54, was one of four people fatally shot inside a Tulsa home on November 23, 2013. The other victims named were Charlie Dake Jr., his wife Melissa Dake, and Tammy Brunson. A fifth person inside the residence suffered minor injuries and survived, and children who were present were unharmed.

The quadruple homicide remains unsolved. Investigators have pursued a variety of leads and questioned the surviving adult, and authorities have said they examined possible motives that included a drug-related angle, but no suspects or arrests have been publicly identified. The house where the shootings occurred has since been left empty.

Does anyone have information about that day, or recall anything unusual in the neighborhood around November 23, 2013?
