San Antonio police on Wednesday morning arrested a man accused of beating a disabled man to death on the city's east side.
The incident happened in the 2400 block of Wyoming and is the city's first homicide of 2014.
Family members identified the victim as Albert Gonzalez, 27.
Rose Gomez, who lives at the home where the incident occurred, said her New Year's Eve party was winding down when Gonzalez and the suspect decided to continue drinking outside.
Homicide detectives are still trying to determine the motive behind what happened next.
"[The suspect] took a sledgehammer and hit the victim over the head several times, killing him," said SAPD spokeswoman Sandy Gutierrez.
Gomez said she was asleep when the incident occurred, but she finds it hard to believe that Gonzalez, who suffered from spina bifida, would have started a fight.
"The other person who was here celebrating the new year with us lost his mind or something," she said. "By all means, I'm not defending him. I'm the one that called police so they can come get him."
The suspect, identified as 28-year-old Eliseo Altamirano, did not flee when police arrived at the home.
Gomez wept as she offered sympathy to Gonzalez' family.
"Albert was a nice person, He didn't provoke a fight. He didn't do nothing wrong. It wasn't his fault," Gomez said. "I just want to send my deepest condolences to Albert's family. I'm very sorry for what happened."
Gutierrez said investigators are still trying to determine what led to the fatal beating.
"We are still investigating the case, still talking with witnesses and everyone else who may be able to provide viable information to this incident," she said. "At this point, there is no motive to this murder other than they had been drinking all night together."
Altamirano will be charged with murder, Gutierrez said.
