Two men were killed in Brockton in the space of about eight hours Friday, in what authorities said were unrelated acts of violence that led to one arrest so far.
In multiple statements issued Friday, Plymouth District Attorney Timothy J. Cruz described the series of events, beginning with the discovery at 4:47 a.m. of a man covered with blood lying on the porch of a Green Street residence. Prosecutors said the man did not live in the home.
“The unidentified man found on the porch was covered in what appeared to be blood,’’ prosecutors said in a statement. “He was suffering from apparent stab wounds.’’
The man was taken to a Brockton-area hospital, where he was pronounced dead. The name of the victim is being withheld pending notification of his next of kin.
Cruz said that on Friday afternoon, authorities arrested Terrance Terrell Richardson of Frankton Avenue in Brockton. He was charged with murder and armed robbery.
Richardson, 19, is scheduled to be arraigned Monday in Brockton District Court.
While authorities were investigating the Green Street homicide, Brockton police were called to The Lit Restaurant on Ames Street at 12:28 p.m. to investigate a report that a person had been shot, Cruz said in a statement.
The victim suffered multiple gunshot wounds to his chest and was taken to a Brockton hospital, where he was pronounced dead. He was identified by prosecutors as Elson G. Miranda, 21, of Brockton.
No arrests have been made in the Ames Street shooting, and the investigation is continuing, authorities said.John R. Ellement can be reached at ellement@
