Received a call from 313-286-8411
Caller ID said dsami which i'm assuming stands for Deputy Sheriff's Association of MI or something along those lines.
when i answered the phone there was an automated answering stating that "due to the number of calls at this time we are unable to answer the phone. please stay on the line and someone will be with as soon as possible" when they where the ones to call me.

313-286-8411 Received ~6:48 PM on 4/9/08. Confused sound of voices in background, then hung up at their end.

It rang three times, I answered, no one there.  This was the number that showed up on Caller ID
