During a Tuesday afternoon press conference, authorities identified him as 22-year-old Juamada Keller Anderson Jr.
Authorities also announced during the press conference that two more people are now facing charges in connection with the incident.
Markus Seville Morris is charged with one felony count of Felon in Possession of Ammunition or a Firearm, and one felony count of Reckless Discharge of Firearm Within a Municipality. Laurel Larice Ladd Jr. is charged with felony Aiding an Offender.
Police found Anderson with a gunshot wound to his head at the scene on East Third Street on Saturday night.
They arrested 17-year-old Patrick Wilson Battees Jr, who has been charged with Intentional Second Degree Murder for allegedly fatally shooting Anderson.
Police said Sunday no other suspects are being sought, however, during the press conference on Tuesday, they revealed they are looking for Morris and Ladd.
Duluth Police Chief Mike Tusken says police believe one or both of them shot at Battees as he was allegedly fleeing.
Tusken says it was necessary for police to wait to release additional details about Morris' and Ladd's alleged involvement while they gathered more facts.
"The investigation changed from what appeared to be a single victim, and a single suspect to multiple suspects, and so before we wanted to give any more updates, we wanted to be very well aware of what actually happened," said Tusken.
Authorities say both Morris and Ladd are still at large, while Battees is in custody.
Authorities are asking for the public's help in tracking down information regarding the incident.
Anyone with information is asked to call the Duluth Police Department at 218-730-5050.
A GoFundMe page has also been set up to help Anderson's familly with funeral arrangements.
