"A FF is planned for Long Beach Pride this weekend in CA"
Long Beach Pride 2019 - A two-day LGBTQ+ event with live music, community programming, and food and drinks from local eateries. The Long Beach Pride Festival is inclusive and strives to promote an environment that is free from prejudice and bias.
While shooting did happen in Long Beach, it was in no way connected to the "Long Beach Pride" event… Perhaps just a coincidence?
