*The only child of late Kansas City Chief’s linebacker, Jovan Belcher, is now entitled to receive her dad’s million-dollar fortune.

She’s four-months old and in the care of her grandparents. But the family of Kasandra Perkins, the girlfriend the football player killed, is seeking full custody of the child.

It’s about to get sticky.

“Personally, I don’t know why we would want to reward Jovan’s—the murderer’s — family with giving them the baby, but that’s not a legal argument,” lawyer Jon Michal Franks told ABCNews.com.

The baby was initially in the custody of Belcher’s mother, Cheryl Shepherd. But she alleges that the Perkins family tricked her and kept the baby since the funeral of their daughter.

“Cheryl agreed to temporarily allow the maternal relatives [to] take Zoey to Texas for her mother’s funeral,” Shepherd’s lawyer Gretchen M. Gold wrote in an email to the Jackson County, Mo., probate commissioner last week. “The maternal relatives have now ceased communicating with Cheryl Shepherd and have refused to return her calls or return the child to her care.”

Now the families are engaged in a heated custody battle, in two different states to boot. A court date is set for Jan. 22.
