On the late night of November 28, 2015, 34-year-old Tomika Mack was shot and killed inside a duplex on the east side of Indianapolis. India Barnes, also 34, was fatally shot at the same residence, which was being used as a halfway house at the time. Police responding to a call found both women with gunshot wounds. The duplex was reported to belong to the suspect’s father.

Investigators focused on Eric Horton, who was located in Urbana, Illinois and taken into custody days after the killings. Prosecutors charged Horton with two counts of murder; testimony at trial described escalating, threatening behavior by Horton in the period before the shootings, including incidents in which he brandished a firearm. A jury convicted Horton on both counts and he was sentenced to two consecutive 60-year prison terms.

Anyone who knew Tomika Mack, her movements that night, or who has additional information about the duplex or people who were there is asked to come forward.
