It has been three days since an Aggie graduate was murdered outside a College Station bar and police are still putting the pieces of the crime together.

William Rufus Stephens, Jr., also known as "Ruf", was shot in the head early Saturday morning outside P.O.E.T.S. Billiards.

Police believe 36-year-old Christopher Schmotzer, a car salesman at a Bryan dealership, pulled the trigger. However, authorities still don't know why.

News Three talked with Stephens' friends Monday and they are waiting for answers. They're hoping that will bring closure to those who loved Stephens the most.

"He was really happy," Stephens' co-worker Jaime Kennedy said. "He was the happiest I'd seen him in a long time."

Kennedy says reality has yet to sink in.

"I didn't have words; my jaw dropped," Kennedy said.

Kennedy found out Saturday her friend and co-worker, Rufus Stephens, had been murdered.

"It was a life cut way too short," Kennedy said. "We all cared a lot about Rufus. It was an unbelievable tragedy that shouldn't have happened to him."

Stephens had just graduated from Texas A&M University with a degree in Wildlife and Fisheries Sciences. Fishing was his passion.

However, when he wasn't outdoors, he was with friends at Ozona Bar and Grill in College Station, where he worked as a bartender.

"He was kind of like my go-to guy for everything," Stephens' roommate and co-worker, Ben Hancock said.

Hancock says he doesn't know why someone would kill his friend.

"As far as I can tell it just seems like the wrong place at the wrong time kind of thing," Hancock said. "He's not going to get confrontational with anybody. He was a big sweetheart, a really nice guy."

Friends say Rufus did not know Christopher Schmotzer, the man charged with the crime. Police are still searching for a motive.

According to police reports, Schmotzer stared at Rufus Stephens and his friends throughout Saturday night while they hung out at P.O.E.T.S. Billiards. When the bar closed, Rufus and his friend moved outside to play football in the parking lot. Police say Schmotzer watched, and surveillance video allegedly shows Schmotzer driving away shortly after the shooting occurred.

However, it's still not known why Schmotzer would target a man so full of life.

"He (Rufus) always had a smile on his face," Kennedy said. "He was always upbeat and he used his hands to talk a lot. He just would crack you up."

"It's just sad it had to be him," Hancock said.

A memorial will be held this week for Rufus Stephens. Services are Thursday at 2 p.m. at First Unitarian Church of San Antonio.
