Warren Strain, a spokesman for the Mississippi Dept. of Public Safety, has confirmed a fourth person was arrested Sunday afternoon on charges related to the shooting of two Hattiesburg police officers.
Strain said Cornelius Clark, 28, of Hattiesburg was charged with obstruction of justice. Authorities did not release any details on the charge.
Earlier in the day, Strain said Marvin Banks, 29, and Joanie Calloway, 22, were each charged with two counts of capital murder. Banks was also charged with one count of being a felon in possession of a firearm and with grand theft for fleeing in the police cruiser after the shooting.
Banks' 26-year-old brother, Curtis Banks, was charged with two counts of accessory after the fact of capital murder.
Strain said that all four suspects are expected to make their initial court appearances Monday at the Forest County Justice Court in Hattiesburg.
Police officers Benjamin Deen, 34, and Liquori Tate, 25, were shot and killed during a traffic stop late Saturday.
Meanwhile, a steady stream of residents came by the area where the shooting happened, leaving flowers or balloons to honor the fallen officers on Sunday.
Donna Nelson was one of them. She said she and her husband had just picked up their dinner and were returning home when they noticed an unusually large number of police officers out on the streets. When they heard what had happened they said their first instinct was to go out and look for the suspects.
Nelson said, "That is the most disrespectful thing right there, to take the life of a law enforcement officer. They put their lives on the line for us every day. To be taken out senselessly like this, that's horrible."
Alberta Harris heads the Briarfield Neighborhood Association next to where the shooting occurred. She said she knew both Officers Benjamin Deen, 34, and Liquori Tate, 25, personally.
She said, "Both of them had a humble spirit. They cared about the people that they were serving and protecting."
She said at a time when there is a huge focus on the use of force by police officers, incidents like this show the strain police officers are under.
"This shows what our police officers have to endure, just on a routine traffic stop."
