UPDATE: The officer death toll has now risen to five, including the DART officer. The attack is the deadliest on U.S. law enforcement since 9/11.
Initially, The Los Angeles Times reported that three suspects were in custody, and that one other suspect was engaged in a standoff with police. After several hours in standoff, the suspect—who claimed he wanted to "kill white people, especially white officers"—was killed by a bomb detonated by police, CNN reports. Dallas Police Chief David Brown told reporters that the suspect said he acted alone and was angered by "recent police shootings."
Preseident Obama called the shooting a "vicious, callous and despicable attack" on law enforcement.
