The statement is a lyric from the TV On The Radio song Wolf Like Me, which is about sex.

Vandagriff's phone was last detected from a mobile phone tower near Bryant's home in Fort Worth at about 1:30am.

A blue plastic kids wading pool was found near her body. A similar one was found in Bryant's backyard. Bryant's roommate said there used to be two kids pools in the backyard but when police arrived there was only one.

Vandagriff's purse was also found in a bin at Bryant's house.

At 4:41am, Bryant was caught on CCTV buying a shovel from Walmart.

The Dallas Morning News reports that Bryant had recently broken up with his 18-year-old girlfriend, who was forced to call police numerous times when he kept showing up at her work and home.
