Armen Mangasaryan, 29, was arrested Wednesday in Burbank at about 8 p.m., and Arpiar Tergalstanyan, a 20-year-old from Glendale, was arrested early Thursday morning.
Police believe the two men are responsible for the shooting death of a 49-year-old woman at her home on the 4200 block of West Jacaranda Avenue.
"Right now, the motive for the shooting, it may possibly be a failure to repay a monetary debt," said Sgt. Robert Quesada from the Burbank Police Department.
The suspect allegedly rang the victim's doorbell once, then shot her once when she opened the door just after midnight on Tuesday night. Police said the victim had lived in the rented house for just a few months with her boyfriend. Investigators say the victim's boyfriend was home during the time of the shooting.
"He was the one that called 911. So we're talking to him. He is not a suspect. We don't want to give that indication," said Sgt. Robert Quesada, Burbank Police Department.
The woman's identify has not been released pending notification of next of kin. Police said the woman's family lives out of the country, possibly in Armenia.
A black Mercedes has been confiscated that witnesses said they saw at the scene.
Both suspects are being held without bail at the Burbank City Jail. They will be arraigned on Friday.
