Three people were killed in Auburn, Alabama, on Sunday after an argument at an apartment complex turned violent. Two of the victims were former members of the Auburn University football team. Auburn Police Chief Tommy Dawson announced the deaths.

Tommy Dawson: “It’s sickening that these young lives were cut short, and also the shooter is such a young man. You know, as a society, we’ve got to learn the value of life again. If I could bring them back today to their parents, I would. Unfortunately, I can’t do that. And to the parents and the families of these victims, I am very sorry. Please let it be known, we’re grieving with you.”

In other gun violence nationwide, four people were killed in an apparent gang-related shooting in Sacramento on Sunday, and four people died when a father in California’s Fresno County killed his wife and two children before taking his own life.
