DALLAS, Texas (CNN) — Dallas is marking the first anniversary of the nation’s deadliest attack on law enforcement since 9-11.
A memorial motorcycle ride got underway Saturday, to honor five officers who were gunned down on July 7th, 2016. The city is holding a number of other memorial events throughout the weekend.
Police said Micah Johnson ambushed the officers at the end of a peaceful protest against police shootings. Nine more officers were injured, along with two civilians, before Johnson was killed by police.
The attack is still considered an open investigation.
