As the case entered day six on Thursday morning, Dec. 18, the gunman in theBrown University shootingthat killed two students and injured nine others remained at large, as authorities pleaded for the public's help in the investigation.
So far, the FBI and Providence Police Department investigators have not been able to name a suspect in the Rhode Island case that garnered national attention and left the victims' families, friends and community mourning and in fear.
One day earlier, on Wednesday,police on social media released a map showing streetswhere they said the person of interest in the fatal Dec. 13 mass shooting was spotted the day of the incident.
The move came on the heels of authorities earlier releasing security camera images and footage of a masked man they believe to be a person of interest, based on witness accounts from survivors.
"He could be anywhere," Providence Police Chief Oscar Perez said of the gunman at a news conference that day, where police remphasized a motive in the suspect's shooting remained unclear. "We still don't know who the person is or where he is."
Providence police and the FBI hope the map and previously releasedphotos and videoswill generate tips from the public to help identify the suspect. Authorities have been canvassing nearby neighborhoods and have received hundreds of tips in the days since the brazen attack.
The shooting is the latest incident of gun violence that hasrocked the nation, and the lack of information and identification on the shooter has left Providence residents and the Brown University community on edge.
Here's what we know about the shooting and ongoing investigation:

Deadly shooting occurred during final examinations
The shooting occurred shortly after 4 p.m. local time on Dec. 13 in an engineering building with unlocked doors as students were studying or taking final exams. Authorities said the suspect opened fire with a 9mm gun inside a classroom and then fled.
The attack prompted a campus lockdown that left students barricaded in rooms or hiding for hours. Investigators later recovered 9mm shell casings from the scene.
Brown University, which has nearly 11,000 undergraduate and graduate students, is considered one of the oldest and most prestigious colleges in the country. Brown was founded in 1764 and is located in Providence, Rhode Island.

Why was Brown University attacked?
Though Perez previously said investigators believe the suspect "definitely targeted Brown University," they still have not identified a suspect. The shooter's motive remains unclear.
Authorities have warned the public to refrain from speculation and spreading misinformation.
Rhode Island Attorney General Peter Neronha has said there is "nothing to indicate motive at all related to ethnicity or political outlook." "That is a dangerous road to go down," said the attorney general, adding that while one or two witnesses heard the shooter "shout something," others did not.
On Dec. 16, Brown University released a statement dispelling rumors about a potential suspect, urging the public not to target individuals. The university had removed a webpage featuring a community member and said there was "harmful doxxing activity."

Investigators release images, video of person of interest
The Providence Police Department released new images on Dec. 17 of a person they seek to identify and speak with, saying they are "close enough" to the person of interest. The grainy photos showed a man wearing a jacket over a hooded sweatshirt, his face visible, walking along a street.
"This is a person we would like to speak with," Perez said, describing the person as someone "who may have information relevant to the investigation."
The new photos came a day after local police and the FBIprovided enhanced images and videoof the masked man walking through neighborhoods near the Ivy League university. The footage, which was mostly taken from residential doorbell cameras, showed the potential suspect in the area before and immediately after the shooting.
In one video, the suspected shooter can be seen leaving the scene of the shooting as a police car with flashing emergency lights arrives. Another video shows the suspect walking along that street just minutes after the attack.
Investigators believe it was likely the person was "casing" the scene, according to Perez, who has noted that the person was more than likely the suspected shooter and not just a person of interest.
Public's help in identifying the person of interest
While the man in the video is masked, authorities hope the images and video will help someone recognize the person's body, gait, movements, or posture. Perez has also called on residents who live in the area to check their security cameras for any possible sightings of the suspect.
The police chief said about 200 tips arrive each day, and as of Dec. 16, they had 200 "actionable" tips.
The FBI is also offering a $50,000 reward for information that leads to the identification, arrest, and prosecution of the shooter, whom law enforcement described as "armed and dangerous."
Perez called the manhunt "probably the most intense investigation that we have in this nation." Providence Mayor Brett Smiley said he shared the feelings of the city's residents and Brown students who were "restless and eager" for an arrest.
Investigation hampered by lack of security cameras in area
Authorities have said the investigation has been hampered by a lack of security cameras in the university's engineering building and in the nearby area.
Early on Dec. 14, the FBI and local police announced they haddetained a person of interestin the shooting. But authoritiesreleased the unnamed man, who was in his 20s, that evening because evidence "now points in a different direction."

Days-long manhunt for suspect in high-profile attack
Though it is rare for a perpetrator in a high-profile attack to evade capture for multiple days, it is not unprecedented.
"This is outside of the norm," Felipe Rodriguez, a former New York Police detective who now teaches at the City University of New York's John Jay College of Criminal Justice, told Reuters. "Mass shooters, by large, are usually killed at the scene or quickly captured."
Recent incidents include the search forLuigi Mangione, the man accused of killingUnitedHealthcare CEO Brian Thompsonin December 2024. Mangione had eluded authorities for five days before he was captured in Pennsylvania after he was spotted eating at a McDonald's by a customer and an employee who believed he resembled the gunman.
In September, the suspect in the shooting ofprominent conservative activist Charlie Kirkwas taken into custody after a 33-hour manhunt. The suspect, who was identified asTyler Robinson, was arrested after a relative and a family friend alerted local law enforcement that he had made comments suggesting he had committed the murder, authorities said at the time.
