Sources close to the investigation tell ABC13 the suspect is 26-year-old Montavius Wright.
On Wednesday, at about 11:58 a.m., officers received a call of a shooting at 3800 Cummins.
At the scene, police learned the shooting happened on the 10th floor of the building, but the suspect was not found. After a search, authorities said the suspect was arrested at a high-rise apartment complex in the 1600 block of Fannin Street around 2 p.m.
Police said the suspect is an employee at Greenway Plaza and the victim was his supervisor. Police believe the suspect targeted his supervisor as he "passed up everybody else." But it's unclear why he targeted the supervisor.

"We do not think this was random, but that he was actually looking for his supervisor," according to HPD Executive Assistant Chief Larry Satterwhite.
Around 1:20 p.m., Houston Police said the scene was no longer considered an active shooting incident.
Several different businesses office out of the Twenty Greenway Plaza building where the shooting happened.
William Contreras, who works on the fifth floor of the building, told ABC13 he stepped out to get lunch for his teammates and by the time he got back, he saw the police cars outside the building, found out about the situation and alerted his coworkers who were still inside.
"I pinged them through Teams and I told them, 'Hey, there's an active shooter in the building,'" said Contreras.
He said the whole ordeal made him uneasy.
"It's going to be definitely crazy going back. I am not from this country and in my country we don't have shooter situations like this. It seems this is rampant in the States," said Contreras.
Another employee ABC13 spoke to, Chris Idol, works on the sixth floor of the building. He too stepped outside for lunch and said he came back around 15 minutes later, only to find out about the situation.
"I feel lucky... Because could you imagine being in there and not knowing? It's nuts," said Idol.
He told ABC13 some of his coworkers were sheltering inside one of the rooms within their office.
