Authorities are investigating a deadly motorcycle crash on Route 202 in Norristown on Tuesday night.
Alonzo was among the witnesses who saw two motorcycles racing before the deadly accident:
"I saw the two motorcycles zipping up and down. These are the two main drag strips, coming over the Airy Street Bridge or the Marshall Street Bridge, which is one block over. I was heading out to the store last night and they came hot dogging up Marshall Street. I saw one lady on the back of one bike and another young lady on the back of the leade bike."
One of the bikers apparently hit a cement guard rail on the Dannehower Bridge. The impact threw the female passenger over the side. Her body was pulled out of the river about five hours later. She was later identified as Ryan Benita Benjoman, 19 (right).
The male driver, not immediately identified, was taken to Hospital of the University of Pennsylvania. There was no immediate word on his condition.
The north and southbound lanes on the Dannehower Bridge were closed for a time but reopened early Wednesday.
