So from the last part we got to the history of Savannah Sanders.
The police finally proceed with the investigation.

They got bits of hints which led to the further discovery of truth.

But to catch a truth is not as easy as that.
The postmortem report said that she was brutally murdered with a sharp knife.

Dr.Williams said to the police that the body was conscious after she was brutally murdered for an hour or two.But at as the injury was severe she died.

The police tried to call Samuel Sanders but no one picked up his phone.
Next they called Claire Sanders.Dhe picked the call and asked the officer "Sir did you get to know who murdered my only daughter".
Officer replied "No madam!We are trying our very best to find the criminal.."
Mrs.Sanders started crying over the call.As she sobbed she said "Please officer tried to find the criminal who snatched the only daughter and love of my life. "
Officer said "Please give us some more time to find the criminal at the earliest." Next the officer asked "What happened to Mr.Samuel Sanders."
Claire replied "He died 6 months ago."

The officer felt sorry for the poor lady who lost her daughter and husband in just a tenure of 6 months.

The officer hanged up the call and called the detective agency to come.

The detective arrived in no time.

Officer Rogger gave them instructions for acting like a spy on Savannah's husband Jimmy Walsh.

The detective's arrived at Jimmy's house and disguised themselves as different house helper and promptly reported to the office.

Detective Conan took disguise as his cook
Detective Arin took disguise as a security guard
Detective Fiona took disguise as the maid.

At night they informed the police everything that was happening at Jimmy's house.

The police set the detective at Jimmy's house because they were suspecting him for the reason as his wife was about to be a billionaire and the CEO of a multinational company.

He wanted to be rich but instead his wife got rich which made him angry.
But the police can't just arrest him like that as he is the husband of Savannah.So they thought of spying to him to get some news.

But little did they know that the crime was done by two people instead of one.
Everyone knew that Savannah Sanders did not have any siblings.
But she had a sister who was two year older than her.
The police got to know this thing when Claire came to the office to tell this big truth.

So Savannah's step sister's name was  Jasmine Cyan.She was the daughter of Claire and her ex-husband Jared Cyan.

But they had a separated for some reason and after that Claire married Samuel Sanders.

The police was all shocked to hear about sister.

So still the police could not find out who had murdered Savannah.

They expected a bit that the crime was done by Jimmy Walsh.

But a larger thing was still left to be discovered.
