What Really Happened to Laci Peterson

This is my opinion on what happened to Laci Peterson.
First of all, Scott claims he couldn't have killed Laci that morning, because he was logged into his work computer the time same people think that he supposedly killed Laci.
Well, he didn't kill her on the 24th.. he killed her the 23rd.
Her body was wearing the same pants her sister had seen her in the night before.
I think that after Laci talked to her mother on the phone, she went upstairs to bed.
Sometime after that Scott put his hands around Laci's neck and knelt on her chest.
He choked the life out of her.

Scott put her body in a blanket or tarp and put her in his vehicle before the sun came up.
He got ready for work and cleaned up.
Either let the dog out with the leash on it, or took the dog with him and let it out somewhere.

Then he went to his office.
He sent some emails, so it would look like he had an alibi.
He put her on is boat with the anchors and such, went out onto the lake and dumped her body.
He took the boat back to his office, cleaned it up the best he could and doused it with gasoline.

Scott goes home, about the same time he did everyday.
He gets cleaned up again and makes sure he didn't miss anything.
Then he informs the in laws Laci is missing.

Some people think that the robbery across the street had something to do with Laci's disappearance and ultimate death.
The burglary happened between 4 and 7 am, so... nope.

Some people say they saw someone they thought was Laci, walking her dog after 10 a.m.
This could be true, but it could also be false.
Police found another woman, that looked a lot like Laci, walking a dog that looked similar to hers.

What do you think happened to Laci?
Do you think Scott is guilty?
