PROVIDENCE, R.I. (AP) — Additional police were sent to Providence schools on Tuesday to reassure worried parents that their kids will be safe with the Brown University shooter on the loose and no indication yet that investigators have zeroed in on a specific suspect in the weekend attack.

Authorities Monday of the man suspected in Saturday's mass shooting inside of a Brown classroom, which killed two students and wounded nine others. After releasing a person of interest in the case on Sunday because the evidence pointed elsewhere, they pleaded with the public for any tips that might help them catch the attacker.
