Narrative:
Aircraft #2 departed runway 12L heading 105 degrees. Aircraft #1 departed runway 12R heading 110 degrees. Simultaneous departures at rsp need 15 degrees divergence. Both aircraft contacted north departure and were radar idented. Local control called south departure to tell him to turn aircraft #1. South departure told north departure to turn aircraft #1 but separation was lost immediately after takeoff. I was working north departure and recognized the problem when I received the flight progress strips. I did not turn either aircraft because we were told to trust that the tower has everything under control.

Title: M98 CTLR DESCRIBED INCIDENT WHEN TWR RELEASED 2 DEPS ON PARALLEL RWYS WITHOUT PROPER SEPARATION.
Narrative: ACFT #2 DEPARTED RWY 12L HDG 105 DEGS. ACFT #1 DEPARTED RWY 12R HDG 110 DEGS. SIMULTANEOUS DEPS AT RSP NEED 15 DEGS DIVERGENCE. BOTH ACFT CONTACTED N DEP AND WERE RADAR IDENTED. LCL CTL CALLED S DEP TO TELL HIM TO TURN ACFT #1. S DEP TOLD N DEP TO TURN ACFT #1 BUT SEPARATION WAS LOST IMMEDIATELY AFTER TKOF. I WAS WORKING N DEP AND RECOGNIZED THE PROB WHEN I RECEIVED THE FLT PROGRESS STRIPS. I DID NOT TURN EITHER ACFT BECAUSE WE WERE TOLD TO TRUST THAT THE TWR HAS EVERYTHING UNDER CTL.
