Narrative:
Air carrier X inbound from south for runway 12L, air carrier Y inbound from northwest to runway 12R. Strong south winds for PA28 showing 60 KIAS. PA28 issued traffic, had visual and stated he would maintain visual. Air carrier X told of traffic and cleared to land. PA28 was north of CRJ2 on parallel course. PA28 started sharp right turn to go behind crj, but crj got a TCASII and went around, from 2 mi final. Problems: crj on north local frequency. PA28 on south local frequency. Couldn't hear each other. Air carrier X didn't trust PA28. PA28 is the assistant air traffic manager at ZZZ ATCT. He routinely gets priority from ZZZ tower and this time it caused an air carrier to go around.

Title: ZZZ CTLR DESCRIBES CONFLICT DURING ACFT VISUAL SEPARATION PROC WITH TFC LNDG ON PARALLEL RWYS.
Narrative: ACR X INBOUND FROM S FOR RWY 12L, ACR Y INBOUND FROM NW TO RWY 12R. STRONG S WINDS FOR PA28 SHOWING 60 KIAS. PA28 ISSUED TFC, HAD VISUAL AND STATED HE WOULD MAINTAIN VISUAL. ACR X TOLD OF TFC AND CLRED TO LAND. PA28 WAS N OF CRJ2 ON PARALLEL COURSE. PA28 STARTED SHARP R TURN TO GO BEHIND CRJ, BUT CRJ GOT A TCASII AND WENT AROUND, FROM 2 MI FINAL. PROBS: CRJ ON N LCL FREQ. PA28 ON S LCL FREQ. COULDN'T HEAR EACH OTHER. ACR X DIDN'T TRUST PA28. PA28 IS THE ASSISTANT AIR TFC MGR AT ZZZ ATCT. HE ROUTINELY GETS PRIORITY FROM ZZZ TWR AND THIS TIME IT CAUSED AN ACR TO GO AROUND.
