The bodycam video shows both officers arriving at a house in the 12000 block of Barron Road just after 11 p.m. on April 29, 2017. The homeowners were out of town and their son was hosting a party that attracted roughly 150 to 300 high schoolers, prosecutor Michael Snipes said. But at around 11 p.m., a neighbor upset about the traffic called police.

When Gross and Oliver arrived, the footage shows them walking into the house as handfuls of teenagers run outside to leave. As Gross talks to the boy throwing the party, 12 gunshots can be heard outside, along with panicked screams.
