Case File No. 00.09.2208 On the evening of September 1 st at
approximately 0200 hours, dispatch received an anonymous phone call
reporting suspicious activity off of 32 Ave and the Gratigny, an
area full of metal factories and warehouse known as Metal Row. Upon
investigation, Miami-Dade police officers discovered the body of
Mr. Dennis Ettie, a 45-year male delivery man, in one of the dark
alleys of Metal Row. Time of death was recorded at 0100 hours.
Cause of death is documented as asphyxiation followed by
post-mortem lacerations. The only evidence found at the scene were
tire tread marks and a strange metal scattered around the body. The
identity of the metal is unknown, but investigators have concluded
that the metal came from the suspects vehicle. The identity of the
metal will lead investigators to identify the metal factory the
vehicle came from and thus lead to the capture of the perpetrator.
The night shift logs were checked at all the warehouses and
factories and the following suspects were taken in for questioning.
All have denied know Mr. Dennis Ettie, however, none of the five
suspects have an alibi for the night of September 1 st and all were
clocked in at their factories and warehouses. It is now up to the
Forensic Investigators of Hialeah Gardens High to determine the
identity of the unknown metal which will lead detectives to the
capture of the murderer of Metal Row.
