Deandre Tyre Demisse Jr. of San Francisco reportedly encountered a group of three men and a 17-year-old girl shortly before 4 p.m. in the northwest parking lot of Southland Mall on Southland Drive, according to Hayward police Capt. Darryl McAllister.
Some sort of struggle then took place over the jewelry one of the men was wearing, and Demisse apparently ended up with a piece of the man's jewelry before the group began chasing Demisse on foot through the parking lot, McAllister said.
The chase led Demisse and the group to a neighboring retail complex and into the Game Shop, where one of the men shot Demisse, McAllister said.
It was around that time mall security called police to report two men chasing another man through the mall parking lot, McAllister said. Police began to receive numerous calls from businesses in the mall area that a shooting had taken place.
When officers arrived, Demisse was found on the floor of the Game Shop suffering a single gunshot wound to the head, McAllister said.
Demisse was transported to Eden Medical Center where he died about 30 minutes later, according to McAllister.
Officers arrested two of the men, 19-year-old Pleasant Hill residents Dijon Newton and Rashad Johnson, moments after they tried to run from the shooting, McAllister said.
The third man involved in the parking lot confrontation, 20-year-old Dalaw Ambers of Oakland, and the 17-year-old girl were detained by officers near the scene shortly after the shooting as well, according to McAllister.
Newton, Johnson and Ambers were booked into Hayward City Jail while authorities investigate the murder, and the teenage girl was released to a parent, McAllister said.
Anyone with additional information is asked to call the Hayward Police Department's Criminal Investigations Bureau at (510) 293-7034.
