And he knew that he wasn't a weakling.

He was an ex-marine trained in combat.

Hell, he was even Mickey's bodyguard.

So Mickey wondered, how the hell did a little teenager get one over on him?

Mickey thought something was being covered up.

And he had a theory.

Lana committed the crime after catching Johnny in bed with the underaged Cheryl.

Was there any proof to this claim?

Well, not exactly.

According to author Casey Sherman, Mickey thought Johnny would have defended himself if he saw Lana and the knife coming, so he must have been distracted by something else, i.e.

being in bed with Cheryl for Lana to sneak up on him.

However, it does make me think of two other incidents, examples that show Lana would be capable of murdering anyone who harmed her daughter.

Before dating Johnny, Lana was married to her fourth husband, actor Lex Barker.

He was perhaps best known for playing Tarzan in a series of 1950s films.

What wasn't known was that for about three years, Lex violently sexually abused Cheryl.

It started when Cheryl was just 10.

When 13-year-old Cheryl finally told her mother, Lana went into her bedroom.

She saw Lex sleeping and picked up a revolver.

Lana put the gun to his head.

She held it there, debating if she would pull the trigger.
