It means she went to Duke at 1:22 in reference to a rape.
The AV doesn't arrive at Duke until 2:30 or so, and she didn't report the rape until well after 1:22 anyway, when she got to Duke Access.
It wouldn't take Sutton but a couple minutes to get to Duke ER.
LTC8k6,
1:22 am is THE TIME that Shelton got the first call. Shelton is the Case officer.
That's where that time originated. It may be confusing, but she doesn't say I'm at Duke at 0122 or I arrived at Duke at 01:22.
She says responded to a approximately 0122 call.
