Jurors on Friday saw an explosive and often times confrontational interview that took place between homicide detectives and a teenager accused of killing his twin brother.
The videotaped interview took place several days after Derris Lewis' brother, Dennis, was shot and killed in the family's Loretta Avenue home, 10TV's Patrick Bell reported.
The questioning came after DNA revealed Dennis Lewis' blood was smeared on his brother's bedroom wall.

Investigators said that Derris Lewis' palm print was contained within the blood evidence.
Columbus police Detective Jay Fulton repeatedly asked the teenager in the interview to explain the evidence.
"We can't find out who did this to your brother until you explain what's going on with your palm print in blood on the bedroom wall," Fulton said. "Who did this?"
"I don't know," Derris Lewis said. "I really don't know. I'm positive. I do not know. I know I was not there. I know for a fact I was not there."
Prosecutors believe the palm print showed that Derris Lewis was in his brother's room on the night of the slaying.
Defense attorneys believe that someone else committed the crime.
Lewis' longtime girlfriend, Kristian Holloway, took the stand on Friday afternoon to defend the man she loves.
With tears in her eyes, she described how much her boyfriend loved his twin brother.
"They were so close," Holloway said. "They did everything together. They were always together. They went everywhere together."
Defense attorneys quickly got to the alibi, 10TV's Cara Connelly reported.
Holloway said that she and Derris Lewis were asleep in bed at the time of the slaying and said that she would not lie to protect the man she loves.
"I mean, it's morally incorrect," Holloway said.
Prosecutors tried to poke holes in the alibi, saying that Holloway might have slept through Derris Lewis leaving the house. She disagreed. Prosecutors were far more successful questioning the credibility of another eyewitness, Derell Tanner, a neighbor.
"I saw three dudes running on the side of the house toward Hudson (Street)," Tanner said.
According to Tanner, he saw the entire crime from his bedroom window. It is testimony crucial to the defense because they maintain that several men killed Dennis Lewis and Derris did not act alone.
Their key witness was not as quick to answer other questions in court, asking if he had to answer how he supports himself.
"I've just been a freeloader," Tanner said.
The defense will resume its case on Monday morning.
