The man, identified by the medical examiner's office as 40-year-old Jose Chuc Mul, was critically injured in a large fight reported around 2 a.m. on Oct. 16 near the intersection of 16th and Valencia streets, according to police.
Chuc Mul passed away four days later, according to the medical examiner's office.
Police spokesman Officer Albie Esparza said the death is considered suspicious but has not been ruled a homicide because investigators have not determined the cause of death.
The brawl involved five suspects who fought with Chuc Mul and another person, Esparza said.
No arrests had been made in the case as of this morning.
