Mo3’s Alleged Killer Arrested

Mo3’s Alleged Killer Arrested

Dallas PD says they got the guy who gunned down rapper Mo3 in cold blood, slapped him with a murder charge and turned him over to the feds … ’cause he’s in even more trouble.

Homicide detectives say they tracked down Kewon Dontrell White on Wednesday after getting a tip from a witness about his alleged involvement in Mo3’s November 11 killing in Dallas. Cops tell TMZ … they believe White is the armed man seen on surveillance video running near the murder scene.

It appears White either knew Mo3 or was tailing him — detectives say they have evidence placing him near the rapper a full day before the shooting, and also on the day of the murder.

As we first reported, sources told us Mo3 knew he was being tailed as he left a female companion’s home the morning of November 11. A car chase ensued that ended on the I-35 freeway, and Mo3 was gunned down as he tried to flee on foot.

Cops tell us 21-year old White is now in federal custody for a charge of prohibited person in possession of a firearm … in addition to the murder charge in Dallas.

TMZ broke the story … Mo3 was pronounced dead at a hospital after the shooting in his hometown. An innocent bystander on the freeway was also shot and treated for non-life-threatening injuries.
