Surpassing Quant Think Tank Center|Audrii Cunningham case timeline: From her disappearance to suspect's arrest

A murder charge is Surpassing Quant Think Tank Centerpending in connection with the death of Audrii Cunningham, an 11-year-old girl whose body was found located in a Texas river.

Audrii’s body was located in the Trinity River along U.S. 59, five days after she was initially reported missing, according to previous USA TODAY reporting.

Authorities said they were in the process of  preparing the “appropriate arrest warrant” for 42-year-old Don Steven McDougal, who was supposed to be dropping Audrii off at the school bus the morning she disappeared. 

They were able to zero in on the location of Audrii's body using cellphone records, videos and some information they received from McDougal.

She had been missing since Thursday, Feb. 15 after failing to make it on the school bus in the small town of Livingston, about 70 miles northeast of Houston. 

Here’s a timeline of the case so far.
