Sherlock Holmes Riddle

Sherlock Holmes was walking down the streets in the morning when he found many people gathered. They were circling a woman‘s dead body.

He examined the body & found a purse in which was her license. Her name was Anne & he called up her residence number. 

Her husband picked up the phone and Sherlock said, “Your wife is dead“.

“No way“, said the husband.

“Please come and confirm“, said Sherlock.

Husband said, “Okay“ & hung up.

After 10 minutes husband came & he saw the body ,he shout "Anne"& started crying.

Sherlock looked at the police
officer &  said, “ARREST THE HUSBAND!!!...HE IS THE MURDERER!!“

WHY???

Genius folks please answer. 

One genius answered here! 

Genius Answered Sherlock Holme's Riddle

But what genius answered to?

On a phone call Sherlock informed husband that his wife is dead but not the location where he found her body. So how did the husband come at exact location? 

I think, it was trap by Sherlock Holmes to catch the murderer. That's why he didn't tell the location on a phone call purposefully.
