Condemned inmate Gregory Summers remembers making funeral arrangements for his parents and an uncle.
All were fatally stabbed and then burned when their home in Abilene was set on fire in 1990.
But investigators in Abilene later determined Summers arranged for the slayings to collect insurance money.
Final appeals are pending for Summers, who faces execution Wednesday night in Huntsville.
He would be the 22nd Texas death row inmate to have his punishment carried out this year.
The victims were Gene and Helen Summers, and the mentally retarded brother of Gene Summers -- Billy Mack Summers.
The attacker -- Andrew Cantu -- was executed in 1999.
