Tyrelle Shaw, the 25-year-old homeless man sought by police for bias attacks on Asian women in Manhattan, took his own life and died alone at the end of a rope in a building on Madison Avenue, police disclosed Tuesday.

Shaw's decomposed body was found hanged inside 766 Madison late Monday, four days after he sent a message on social media that he was preparing to kill himself, NYPD Chief of Detectives Robert Boyce said.

"He is one of the most strangest stories I have had in quite some time," Boyce added, as he recounted Shaw's recent history in which he admitted assaulting four Asian women over a five-day period, ending June 15 with an attack on Mulberry Street.

In each instance, according to police, Shaw tried to get the attention of the women or engage in conversation with them.

Rebuffed, Shaw struck them with a hard object in a plastic bag and then fled, investigators said.

Shaw complained during the attacks that Asian women wouldn't pay attention to him and that he felt frustrated, police said. After the media circulated surveillance videos showing Shaw's face, people called police and detectives were able to identify him.

Shaw posted on social media where, according to Boyce, the man admitted to all of the crimes.

Since Shaw was homeless and estranged from his family, he proved hard to locate, Boyce said.

Shaw called himself "Mr. Talented" on his blogs and he seemed educated.

Officers monitored the last communication from Shaw on June 18 in which he said he was going to commit suicide.

When police discovered Shaw's hanged body, a bag containing a hammer that cops believe was the object used in the assaults was near his feet, Boyce said. Also in the bag was a cellphone and a suicide note in which Shaw admitted to the crimes, Boyce said.

Adding to the strangeness of the case was that Shaw had no prior record of assaults and being violent.

"A strange case to say the least, and now it is over," Boyce said.
