Suspect in Dallas shootings suspects in four cases in Tennessee

Authorities in Tennessee have identified four people who were killed in an apparent murder-suicide in a Memphis suburb.

The four victims are identified as Robert Anthony Jones, 38, who was a suspect in a murder-for-hire plot to kill two men and injure a third, authorities said.

Authorities identified Jones as a suspect who was in possession of a weapon and a knife in the shootings and a fourth person who was injured in the shooting but did not know who he was.

The motive for the slayings remains unclear.

The suspects were wearing masks and black hooded sweatshirts when they were shot, according to the FBI.

Authorities have yet to release details about the motive for either of the shootings.
