More - Flynn: 4th of July Shootings Gang-Related

The request from family members of one of four murder victims in a north side July 4th murder: turn yourself in.

"This was a senseless act by a person who doesn't have a heart, that is a coward," said Harold Raddle, the uncle of murder victim Theresa "Tutu" Raddle.

Raddle is calling for family members of whoever killed her, Kendrick Jackson, Jacoby Claybrooks and Marielle "Tina" Fisher.

"Somebody knows who it was. He's somebody's brother. He's somebody's son. He's somebody's nephew.

"They need the young man to do the right thing."

Robert Warrens, one of Raddle's cousins, adds to the call for suspect information to come to the light of day.

Milwaukee Police believe the victims have connections to the Chicago-based gang "Murda Mobb."

That's not the perception family members of Kendrick Jackson has of their now-dead brother.

"Ken was not affiliated with (a) gang," said Latasha Johnson. "It was not about (any) gang stuff."

"We don't (have anything) to do with (the) Murda Mobb," claimed Kina Jackson.
