On Thursday, Raleigh police arrested the three suspects, Ezavia Allen, 18; Marvin Johnson, 17; and Cameron Morris, 17, for shooting and killing Shirley Newkirk, 63, outside her home in a random robbery early Thursday morning.
Court records show that all three teens have criminal rap sheets of similar charges.
According to public records, Morris has the longest rap sheet. He was charged with felony breaking and entering and having a gun in 2004, and has similar charges this year.
Allen, Marvin and Johnson, each, have been charged with one count of murder and one count of attempted robbery with a dangerous weapon.
Police also say the three teens made a similar robbery attempt about a mile from Newkirk's home on East Lane Street where they are also charged with attempted murder for shooting at a man inside his car. No one was hurt.
There had been some speculation that the shooting was gang-related, but the lead investigator said robbery was the only motive.
During their investigation, police recovered two guns, but are not releasing any other information.
Police said Newkirk was in her car getting ready to go meet friends for a regular early-morning walk when she was shot. When officers arrived to the scene of the crime, they found Newkirk had crawled back to the house where she died.
Newkirk leaves behind a husband and two daughters.
The suspects are in jail without bond.
