January 22, 2014, GARLAND (ABC) — Garland police arrested 18-year-old Colten Jon Moore Wednesday  and charged him with capital murder in the robbery and murder of a 7-Eleven store clerk.

Moore was taken into custody after a search warrant was executed in the 2900 block of Creek Valley Drive.

Bond was set at $1 million.

Records show Brown has been previously arrested in Brown County for possession of marijuana.

It was before daylight Tuesday morning when a man wearing a mask and carrying a rifle with a scope shot and killed store clerk Yosef Tulu and then walked right out the door with a bag in his hand.

The store is located at 2509 Northeast Firewheel Parkway in Garland.

The Oak Park School, a childcare center, is just across the street from the store where the 31-year-old immigrant was gunned down. Owner Renee Crissey said even though it happened hours before any kids arrived, she put the school on lockdown.

“We did go ahead and do outer doors all locked,” Crissey said. “The kids didn’t go outside to play yesterday.”

Oak Park has surveillance cameras. Some of them face the direction of the store. Crissey spent Tuesday going through all the footage hoping she might see something that would help police.

“The reality is that someone knows this person. And I want them to catch him,” she said. “I don’t want my children out there around him.”

Garland police say tips poured in after they released surveillance video of the shooter. Officer Harn said police had increased their presence in the area.

Late Wednesday investigators briefly put up police tape and appeared to be searching in bushes outside the store, but left less than an hour later.

“We’re following up on everything,” Harn said. “We’re looking for that little clue that’s going to tell us who this was.”

Retired Marine Bob Sawyer has lived near the store for decades. The shooting made him angry.

“He killed that man for no reason at all,” Sawyer said.

Until the suspect is caught, Sawyer said he will be concerned about his safety. He said he was double checking to make sure all his doors and windows were locked.

“I’m a disabled veteran, so there is not a whole lot that I can do to protect myself outside of trying to bash someone with my cane,” he said.

Sawyer added he is keeping a closer eye on his neighbors and his surroundings.

Earlier Wednesday, Dallas-based 7-Eleven Inc. said it would offer a $15,000 reward for information leading to the arrest and indictment of the person responsible for Tulu’s death. To qualify for the reward, persons with information should contact Garland Crime Stoppers at 972-272-8477.

Informants may also submit a written claim for the reward no later than 30 days after indictment to the Asset Protection Dept. at 7-Eleven Inc., 1722 Routh Street, Suite 1000, Dallas Texas 75201.

A total of $25,000 in reward money is being offered. On Tuesday night, Oak Farms Dairy put up $10,000.

Margaret Chabris, a 7-Eleven corporate spokeswoman, said the company has offered outside professional counseling services to store employees. She said the company will help Tulu’s family with the expenses related to transporting his body back to his family in Ethiopia.

A fund has been set up for donations through Chase Bank. The Account number is 555289953, and the routing number is 111000614.

Friends will conduct a memorial for Tulu outside the store on Thursday evening at 6:30.
