A man has been charged with first-degree murder in the shooting death of his father Thursday night inside a downtown Austin condominium, police said Friday.

Hakim Abdeladim, 30, of Lago Vista was taken into custody late Thursday at the Holiday Inn Town Lake hotel, which is across the street from the Towers of Town Lake condos, where the shooting occurred.

Police responded at 7:50 p.m. to reports of shots fired at the Towers of Town Lake, which is along Interstate 35 about two blocks from Rainey Street, authorities said. When officers arrived, they found 66-year-old Nadir Abdeladim inside his home with multiple gunshot wounds, police said.

Police said they believe Abdeladim used an AR-15 rifle, which was recovered inside the residence.

Firefighters and Austin-Travis County EMS medics attempted to revive Nadir Abdeladim but he was pronounced dead at the scene, officials said. Police said several witnesses told police that the victim's son, Hakim Abdeladim, was seen with his father minutes before the shooting and had been spotted leaving the building.

Police had searched by air and on the ground until, around 9:40 p.m, about a dozen police officers rushed into the Holiday Inn and apprehended Hakim Abdeladim in the lobby. He was found with blood on his clothing, authorities said.

Austin police Sgt. Tracy Gerrish told reporters on Friday that Nadir Abdeladim lived in the condo with his wife, who was downstairs in the lobby at the time of the shooting. She said homicide detectives are still trying to determine the motive.

"Unfortunately, Hakim did not want to cooperate so the only two people in the apartment were him and his father, so we don't know if an actual argument ensued," Gerrish said. "I think there are some long-term issues going on with the family."

The Travis County medical examiner was conducting an autopsy on Nadir Abdeladim on Friday, and Hakim Abdeladim was being held at the Travis County Jail, officials said. His bail had not been set.
