Facts:
1. Husband had a past "history" as a young man, which included a divorce, auto theft, and an all-around Bad Boy image
2. Sometime before she died (a week?) she asked the ladies in her Bible study to pray for her since she was "having troubles in her marriage."
3. Ruth Ann Blake Manguno went missing without a trace from her rural home in Folsom, LA, May 1983. Her baby was left in her crib. There were no signs of forced entry.
4. A decomposing human skull appeared in a neighbor's mail box in August 1983 and, using dental records, was matched to Ruth Ann. She was no longer a Missing Person.

Trust Me:
9. Has a reputation for being controlling, sensitive to perceived criticism, and needing attention
10. Has a reputation for treating his family the way he treats his animals: He isolates, emotionally abuses, and controls
My theory:
Ruth Ann Blake was thinking of her daughter's well-being when she started to consider leaving her husband or demanding changes in their marriage, which may have included moving closer to town. During a heated argument, husband lost his temper and accidentally killed her. He spent the next several hours of the night and early morning covering up the accident and disposing of the body before placing his daughter safely in her crib and heading to work, leaving the door open, knowing someone else would eventually "discover" that very day that Ruth Ann was missing. Later, he tried to collect insurance and was told that, without evidence of death, he couldn't make a legitimate claim. Since he disposed of the body, he knew where it was, so he retrieved the one body part that could positively identify her remains: the skull. He then placed the skull in/by a neighbor's mail box, knowing that someone would soon find the skull and call authorities.
More Evidence:
If the above were NOT the case then why do her Blake relatives, (ex)husband, or child re-open this cold case? Why aren't they trying to find the real killer? Trying to save others' the same pain by having this kidnapper/murderer locked up? Doesn't Ruth Ann have siblings, parents, or cousins? Forensics have come a very long way since the early 1980's, and many cold cases from 20-30 years are being solved today.
