The man accused of killing three people and wounding another remained on the loose Wednesday afternoon, Gwinnett County police said. But investigators believe the suspect could be in one of three cities.

Robert E. Bell, 33, may be traveling to Chicago, Albany, Ga., or Crossville, Tenn., Cpl. Jake Smith said.

Bell had been staying in a Snellville-area home for about two weeks when he allegedly shot four people Sunday night during a domestic dispute, according to police. Investigators have not determined a motive in the shootings.

Angelina Benton, 34, Benton's 12-year-old son, Joseph McDonald, and her 19-year-old godson, Raynard Daniel, all died after being shot multiple times at a home in the 4600 block of Anderson-Livsey Lane, Smith said. The three were all originally from Albany, WALB News Channel 10 reported Wednesday.

Angelina Benton’s boyfriend, Justin Cato, 23, was shot in the leg and is expected to recover from his injuries, police said.

All of the victims were residents at the home, and police said Angelina Benton allowed Bell and his wife, Danielle Hill-Bell, to move into the home.

Once arrested, Bill is expected to charged with three counts of felony murder and one count of aggravated assault, Gwinnett police said. Bell is considered armed and dangerous, and anyone with information is urged to call detectives at 770-513-5300.
