I saw a little snippet about this while over at AllHipHop.com today and decide to investigate a little more. Though I couldn't find much recent info, here is what I found as of November 14th. To read the entire article, CLICK HERE FOR MY SOURCE
An arrest was made late last month in murder of La La Brown and JeTannue Clayborne. Milwaukee police arrested Deangelo P. Tatum, 23, on an obstruction charge while investigating the homicides. Tatum was questioned by police Oct. 20, the day after the killings, and denied having any firearms.
Tatum has two teardrop tattoos now, which a witness and cops say are new. He also turns out to have bought handguns of the 9 mm and .40 caliber variety in October 2005 and August 2007, and bought ammo similar to that found at the scene in August. Items seized from Tatum's house, according to the warrant: one 9 mm pistol, one holster, 74 rounds for the gun, assorted other things, and Tatum himself. Not on the "Property Inventory" form as seized property: anything .40-caliber. It was listed that there were 8- .40 caliber cassings found at the murder scene.
