Story highlights Police say Jessie Carlos Javier, 42, carried out casino attack in Manila

Officials say gunman acted alone: 'This is the truth'

(CNN) The lone gunman behind the casino attack that left 37 dead in Manila last week was in debt and had a gambling problem, Philippine police say.

Jessie Carlos Javier, a 42-year-old man from the Philippines, was identified as the suspect in last week's attack in the Philippines capital, said Oscar Albayalde, police chief for the Manila area.

Carlos was separated from his wife and had been laid off from his job. Recently, he was banned from entering all casinos at the request of his wife, according to Southern Police District Chief Tomas Apolinario Jr.

Police believe Carlos, who died from a self-inflicted gunshot wound, acted alone. ISIS had claimed responsibility for the attack Friday, but officials have repeatedly denied it was terror-related.

"This is the truth. This is all the truth," Albayalde told reporters as authorities gave details of the lone assailant.

Philippine police have released these images of the heavily armed suspect in the Manila casino attack.
