Police in Abilene arrested 57-year-old Robert Guerrero Alvarado, Danielle's father-in-law, this afternoon.
He was named in a warrant out of Wichita County.
He's charged with tampering or fabrication with physical evidence and he's being held in the Taylor County Jail on a $250-thousand bond.
He's previously been convicted in Abilene for indecent exposure, and was convicted in Wichita County for indecency with a child.
Robert Alvarado has also been arrested on numerous drug charges.
Danielle's body was found buried off FM 368 near the Wichita River in Burnett Park.
