A Hollywood police officer shot and killed a pit bull in a
resident's back yard while searching for a man who had committed
a strong armed robbery.    It happened just before noon
Wednesday in the 2300 block of Wiley Street. The 4-year-old male
pit bull, named Pup-pup, was shot in the back yard of a home
that he was trained to protect.  "I just heard gunshots as I was
walking back to the house," said dog owner Antonio Williamson.
It happened just after Williamson came outside to ask why so
many police officers were parked in front of his house. They
were looking for a man who had punched another guy in the face
and stole his bike in front of a convenience store on Pembroke
Road and 22nd Avenue. A witness followed the suspect to the area
on Wiley Street and called 911.  "The police suspected the
robber may have gone into the back yard so they entered through
a side gate.  "When they got to the back yard, they were
confronted by a pit bull," said Hollywood Police Sgt. Lester
Cochenour.  The dog was shot multip
