Solve the murder!

I took it quite seriously, I thought.

Well ... 7 people ruining the game that was supposed to be fun and give out a prize is well enough to give away the answer. Thanks for ruining it everyone, hope it was worth it:

Here is the solution >.<:

Guard E. Lou:

The fireman and the driver tell me all they have to do is pull the
whistle and they can be off, so I better get on with solving this
case so we can dump the murderous passenger here and try and
make up time for Constantinople.
First of all let’s begin by eliminating the obvious.
Ivan Ego was understandably furious that his rocket designs had
been pinched, and was witnessed having an argument with
Werner Von Black but I do not think this argument escalated to
murder. How could Werner Von Black give him credit for his
work if he was dead?
After that things get a little more complicated:
Dee Sypher was after the rocket plans and perhaps the man
himself. She was a spy that risked discovery, but I don’t think
she was actually ordered to kill him and so I discount her.
Then there is Herr Cutt and Sigmund Froid. Both of them were
employed to make sure the rocket designs never fell into the
wrong hands. Werner Von Black was worth more to both of
them alive however. So I think we can discount them both,
which leaves us with all of Werner’s lady friends. My goodness
the man got around Heidi Evidence was seen in his compartment, and overheard
giving him a piece of her mind, but she had no need of the plans
so I think it is safe to say she didn’t kill him.
Which just leaves us with Kiki De’Leggs. We only have her
word for it that Werner Von Black was dead when she went to
the compartment. She flashed enough skin to attract the man's
attention and then lured him into a relationship in order to gain
access to the rocket plans. Who knows what happened?
Perhaps, being the womaniser he is he came on a bit heavy, but
whatever the cause Kiki took what was to hand, the stockings
and the tie, and strangled him. In order to disguise the murder
she then knotted a hangman’s noose and pulled him up to the
ceiling. Then she simply hid the plans inside her multi-layered
skirts and legged it.
And so, Kiki De’Leggs I am arresting you for the murder of
Werner Von Black.
Case closed.

...

Kiki De Leggs did it.

That would never hold up any proper court of law.

I think he committed suicide over proposed gun reform, which would have impacted profits from rocket sales.

Thanks Obama.
