Narrative:
Air carrier X called on a visual approach to runway 2 he reported 8 mi southeast. I told him to report a 3 mi right base to runway 2. Aircraft Y was in left closed traffic for runway 2 and was told to report left downwind midfield. When aircraft Y reported midfield; I asked aircraft X his position. He reported 3.5 mi right base. I told aircraft X cleared to land and report turning final. I told aircraft Y to extend downwind. Aircraft X reported turning 1 mi final at 8500 ft. Aircraft Y then reported over a peak about 5 mi southwest of the airport. I told aircraft Y to start his base and he was following a hawker jet. When I finally got the hawker in sight; aircraft Y was on final in front of him. Aircraft Y broke off his final and maneuvered to follow the hawker. Neither pilot gave accurate position reports and wound up in relatively close proximity.

Title: SAF CTLR DESCRIBED CONFLICT EVENT AT 7500 FT BETWEEN IFR ON VISUAL APCH AND VFR PATTERN TFC; ALLEGING POOR PLT POSITION REPORTS AS CAUSAL.
Narrative: ACR X CALLED ON A VISUAL APCH TO RWY 2 HE RPTED 8 MI SE. I TOLD HIM TO RPT A 3 MI R BASE TO RWY 2. ACFT Y WAS IN L CLOSED TFC FOR RWY 2 AND WAS TOLD TO RPT L DOWNWIND MIDFIELD. WHEN ACFT Y RPTED MIDFIELD; I ASKED ACFT X HIS POS. HE RPTED 3.5 MI R BASE. I TOLD ACFT X CLRED TO LAND AND RPT TURNING FINAL. I TOLD ACFT Y TO EXTEND DOWNWIND. ACFT X RPTED TURNING 1 MI FINAL AT 8500 FT. ACFT Y THEN RPTED OVER A PEAK ABOUT 5 MI SW OF THE ARPT. I TOLD ACFT Y TO START HIS BASE AND HE WAS FOLLOWING A HAWKER JET. WHEN I FINALLY GOT THE HAWKER IN SIGHT; ACFT Y WAS ON FINAL IN FRONT OF HIM. ACFT Y BROKE OFF HIS FINAL AND MANEUVERED TO FOLLOW THE HAWKER. NEITHER PLT GAVE ACCURATE POS RPTS AND WOUND UP IN RELATIVELY CLOSE PROX.
