Authorities searched for three suspects after gunmen opened fire in a store in far North Dallas, killing one person and injuring three others.

Police said they couldn't immediately pinpoint a motive for the deadly shooting, which occurred about 9 p.m. Tuesday at The Gas Pipe, a store that sells rolling papers, pipes and other items.

Three gunmen entered the store through the front door. While it's still uncertain what unfolded next, the three left on foot after shooting four people inside the store, said Lt. Craig Miller, Dallas Police Homicide, in online stories Wednesday for The Dallas Morning News and Dallas-Fort Worth television station WFAA.

One victim was taken to Presbyterian Hospital of Plano where she was pronounced dead, Sgt. Bruce McDonald with Dallas Police Homicide told The Associated Press early Wednesday. Police have not released the victim's name but Miller said the person did not work at The Gas Pipe.

Ambulances took three other victims to Parkland Memorial Hospital.

"One is in surgery with a serious wound, believe he will survive. The other two have non-life threatening [injuries]," McDonald said.

Calls by The Associated Press early Wednesday to Presbyterian Hospital of Plano and Parkland seeking comment were not immediately returned.

McDonald said the store was not robbed.

"We don't have any serious leads. We are in the process of gathering evidence, hopefully we can get some ballistics evidence," McDonald said.

He said eight to 10 people were in the store when the shooting started. One of the suspects wore a bandanna, he said.

Michael Harris, a friend of one of the store's employees, was among those outside the store Tuesday night. He had just arrived, planning to give his friend a ride later after the store ceased operation at midnight.

He was alarmed at what happened but relieved when the text message "I'm OK. Call you later, Sarah" showed up on his cell phone. She told him she was at the police station giving a statement.
