Toronto Police have charged two men with first-degree murder in the shooting death of Nnamdi Ogba.

Trevaughan Miller, 19, and Abdullahi Mohamed, 22, were both arrested after the Toronto Police Emergency Task Force executed search warrants at five different addresses early Thursday morning. They made their first court appearance Thursday afternoon and are both scheduled to appear again in court on April 12.

Miller and Mohamed allegedly approached Ogba from behind as he was walking to his parked car near Scarlett Road and Lawrence Avenue West on March 16.

Homicide detectives say the accused shooters fired at Ogba, fled on foot and eventually left the area in an SUV.

At a news conference announcing the arrests and charges, Supt. Ron Taverner said the incident may have been a retaliation shooting in relation to an ongoing "turf war" in the area and said there may be more retaliation in the future.

"That type of event will continue. It's our job to interrupt that, to prevent these things from happening and we're going to go about that in a very proactive way," he said.

Police say Ogba, 26, was innocent. He was working as an electrical engineer at the time of his death.

Investigators are still searching for the driver of the SUV, who they believe was waiting in the area surrounding the Scarlettwood Court community housing complex.​

Family seeking answers

Ogba's family welcomed news of the arrests, which they learned about early Thursday morning.

"We need to know what happened. What went wrong. Who did he offend?" said Ogba's father Sylva Okezie. "He doesn't pick quarrels; he doesn't pick fights with anyone."

Okezie and a few other family members attended the afternoon news conference about the arrests. He said he hopes the investigation will lead to answers about why his son was killed.

"At least we'll be able to know what happened, and who is behind the whole incident," Okezie said. "Knowing that he didn't just die and you cannot find the killers. That hurts more."
