Police have released another image of a person of interest in a mass shooting at Brown University, as they enter the fourth day of a manhunt.
Students Ella Cook and Mukhammad Aziz Umurzokov were killed on Saturday when a figure dressed in black opened fire in a lecture hall at the Ivy League university in Providence, Rhode Island. Nine others were injured.
On Monday, investigators shared several short videos of the person they are now seeking. The videos revealed few details but showed a person all in black walking down a residential street shortly before the crime.
The search for the shooter resumed after officials cleared and released a previous “person of interest” on Sunday.
With no person in custody and a manhunt continuing days after the attack, the community remains on edge.
On Tuesday, police released an enhanced image of the person of interest and described the person as approximately 5’8″ (1.73m) with a “stocky build”.
Rhode Island Attorney General Peter Neronha said there was “no basis” to keep the first person investigators detained in custody, adding that evidence “now points in a different direction”.
Authorities did not say what had prompted them to detain the individual.
FBI Director Kash Patel said his agency is offering a $50,000 (£30,000) reward for information leading to an arrest.
“We are in the 49th hour, and there’s no one that wants to put this individual in handcuffs more than us,” Providence Police Chief Col Oscar Perez told reporters at a news conference on Monday.
Videos released by authorities on Monday show a person wearing a black face mask. The person is also pictured wearing a dark jacket and pants, and a dark woollen cap.
In one video, the person walks past a fence. In another, they cross a street, and in a third they walk down a residential road.
All remaining in-person exams and classes for the semester have been cancelled at Brown University.
