Crime Stoppers is offering a $5,000 reward for information that helps authorities nab Brandon Nathan Teixeira, a 27-year-old murder suspect who's been on the lam for weeks.

The Integrated Homicide Investigation Team announced the reward Wednesday morning in the hopes of generating new tips about the accused killer's whereabouts.

"We believe people have information about where this man is right now," Cpl. Frank Jang said. "We need to find him. He poses a significant risk to the safety of the community."

Teixeira is accused of gunning down 28-year-old Nicholas Khabra in Surrey last year, and authorities warn he should be considered armed and dangerous. An unidentified woman was also injured in the shooting, but survived.

Officers came close to arresting Teixeira on Sept. 6, but he managed to slip away.

IHIT has said it's possible the murder suspect fled to Calgary or Edmonton, where he has associates, and that he might have altered his appearance to conceal his identity. They suggested he might have shaved his hair or hidden his distinctive tattoos.

A criminology instructor at the University of the Fraser Valley and former police officer believes Teixeira will become increasingly desperate as the manhunt continues and could be running out of options.

"I would think he's going to be looking over his shoulder, could be very paranoid because he doesn't know who he can trust, where he can go," Richard Konarski told CTV News. "It's a risk-reward thing because he has to be very careful if he reaches out for help that that person had better be trusted."

Teixeira is described as white, 5-10 tall, 160 pounds with brown eyes and brown hair. He has a snake tattoo on the left side of his chest and a sleeve tattoo on his left arm.

IHIT also released new surveillance video Wednesday that shows Teixeira making a purchase at a liquor store in the Langley area on Sept. 5 – the day before police tried to arrest him.

There was another attempt to apprehend the suspect on Sept. 19 in Langley, which involved members of the Combined Forces Special Enforcement Unit and the Lower Mainland Emergency Response Team, but Teixeira was not found.

Anyone who wants to claim the reward for Teixeira can call Crime Stoppers at 1-800-222-8477.
