It just dawned on me. It is not Natasha OR Cynthia, because they would have both been fingerprinted in 1987.
But!
I started to think about Rebecca, who supposedly died in 1977. Ervil ordered her murder and the two guys, Duane Chynoweth and Ed Marston,
allegedly followed it through. However, BOTH of these men were eventually executed on June 27th, 1988! Smack in the middle of the time period when the 'new' BST arrives in Dallas. Maybe they staged her murder to appease Ervil's demand and then helped to liberate her? I am wondering if FLEK was either 1) Rebecca, 2) Wendi, 3) someone else involved with the killing, 4) someone involved with the escape?
"Eddie and Duane, however, had definite orders from Ervil to see that Rebecca never made it to the airport. Ervil smiled at them cunningly and said, Make her happy. Give her a one-way ticket."
"Ervil ordered Duane and Eddie to dispose of the body. Just before they drove away, Ervil cautioned them, If anyone asks her whereabouts, tell them she ran off to Mexico with a lover.""
"Her unmarked grave has never been discovered."

"Ervil LeBaron grimaced as he looked down at the body of his pregnant daughter in the trunk of his car. Rebecca's neck was chafed raw from the rope her killers had used to strangle her, and a stream of blood had dripped from her nose onto the mat under her head. He slammed the trunk shut."

"However, Duane, Mark and Ed left the church to pursue their own religious beliefs after Ervil LeBaron was convicted in the State of Utah for murder. "

"In May 1988, Heber masterminded an elaborate scheme to carry out Ervil's and Aaron's directives. Heber planned to have the three Sons of Perdition slain simultaneously; no small feat given that Ed lived in Dallas, and Mark and Duane in Houston."

My hesitation in considering Rebecca is that she was the daughter of Ervil and Delfina...and biologically unrelated to the Chynoweths (to my knowledge). Yet, FLEK is the spitting image of Bud!
Since the family seemed to intermarry, men married younger sisters of their own mother's sister wives, etc, maybe Ed was in a relationship with Wendi or Rebecca?
I don't know! I feel tangled now.
