U.S. authorities investigating eye color as key to missing man’s death

U.K. police said Monday they were investigating the disappearance of a man believed to have lost his eyesight as a result of an overdose of heroin.

The 36-year-old man is suspected of killing a woman in July 2015, the London Metropolitan Police said in a statement.

He was arrested in August and charged with murder, but his whereabouts are unknown, police said.

The case was also being looked into by the Royal Courts of Justice in London.

Police said they are now seeking help from the public to identify the man.

In a statement, they said he was not known to the public and they have asked the public’s help in finding him.
