Prosecutors say father's obsession with potty training sparked the rage that led to toddler's murder

DETROIT (WXYZ) - "My daughter is out there. She's out there", said Banika Jones about the little girl she told the jury she believes is still alive, but prosecutors say the toddler was murdered by her father.

D'Andre Lane's trial on charges of murder and child abuse began Wednesday with prosecutors telling the jury that while police never found the body of 2-year-old Bianca Jones, they did find evidence of human decomposition indicating the child had died. 

Prosecutors say Lane is obsessed with toilet training training and claim he lost his temper and beat Bianca to death when she wet herself.

On December 2, Lane told police his little girl was taken during a carjacking around 9:00 am at the corner of Brush and Grand Boulevard in Detroit.

Police located Lane's vehicle about six blocks away with the engine running but Bianca was not in the car.

Lane's defense attorney Terry Johnson told the jury in his opening statement that there is "no bloody scene" and that the stick Lane used to discipline his kids was softened with a "loofah" sponge because he didn't want to hurt them.

Johnson told the jury that they will hear from some of the mothers of Lane's children. Lane has seven children by seven different women.

Johnson said it's too soon to tell if Lane will take the stand in his own defense.

Testimony resumes Thursday before Judge Vonda Evans.

The trial is expected to last several weeks.
