Investigators in Grand Junction are looking into whether Web site postings by a missing woman may have anything to do with her disappearance.
Paige Birgfeld, 34, has not been seen or heard from since Thursday.
The Daily Sentinel reports Birgfeld posted messages on chefsuccess.com indicating she feared the return of her ex-husband, Rob Dixon.
Birgfeld wrote in March that her children asked if their dad was going to kill her.
But Birgfeld's father, Frank Birgfeld of Denver, says it does NOT appear Dixon has been in the Grand Junction area recently.
Paige Birgfeld's car was found ablaze Sunday night in a parking lot about two miles from her home.
Mesa County sheriff's Lieutenant Jim Fogg says authorities have not ruled out a random act of vandalism.
About three dozen family and friends held a candlelight vigil for Birgfeld Monday night to pray for her safe return.
