Narrative:
Light transport X was being vectored for a visual approach to runway 21R. Small aircraft Y was being vectored to follow light transport X. There was also an large transport being vectored for the parallel runway 21L. Light transport X called west local control 8 mi final, and was clrd to land runway 21R. Small aircraft Y was on a parallel course to light transport X's right. Small aircraft Y called tower and was again instructed #2 following light transport X traffic. Small aircraft Y advised tower he had him in sight. Small aircraft Y appeared to be overtaking light transport X. Small aircraft Y was asked if he still had his traffic to follow in sight. He replied with a negative statement, and that he thought he might be following the wrong aircraft (the large transport on final for runway 21C). Small aircraft Y was issued an immediate right turn heading 270 degrees. The targets were merging on radar. Small aircraft X, from the eyes of the tower, appeared to be in front of light transport X and turning west. Light transport X started a climb to avoid traffic. Light transport X elected to continue the approach and land runway 21R. Small aircraft Y was given a right 360 degree turn to final and landed runway 21R west/O further incidence. Callback conversation with reporter revealed the following: reporter gave experience level. No specific distance was mentioned on near midair collision, but targets did merge on the BRITE radar. Traffic had been given to both aircraft and small aircraft had stated the small transport was in sight. Reporter feels that small aircraft had another aircraft and not the small transport in sight. Small transport didn't see the small aircraft until he started a turn to the west, and at that time, small transport pulled up to miss the small aircraft. Location of incident was on final approach runway 21R, approximately 5 mi.

Title: SMA ON VISUAL APCH HAD WRONG ACFT IN SIGHT AND SMT TOOK EVASIVE ACTION TO MISS SMA.
Narrative: LTT X WAS BEING VECTORED FOR A VISUAL APCH TO RWY 21R. SMA Y WAS BEING VECTORED TO FOLLOW LTT X. THERE WAS ALSO AN LGT BEING VECTORED FOR THE PARALLEL RWY 21L. LTT X CALLED W LCL CTL 8 MI FINAL, AND WAS CLRD TO LAND RWY 21R. SMA Y WAS ON A PARALLEL COURSE TO LTT X'S RIGHT. SMA Y CALLED TWR AND WAS AGAIN INSTRUCTED #2 FOLLOWING LTT X TFC. SMA Y ADVISED TWR HE HAD HIM IN SIGHT. SMA Y APPEARED TO BE OVERTAKING LTT X. SMA Y WAS ASKED IF HE STILL HAD HIS TFC TO FOLLOW IN SIGHT. HE REPLIED WITH A NEGATIVE STATEMENT, AND THAT HE THOUGHT HE MIGHT BE FOLLOWING THE WRONG ACFT (THE LGT ON FINAL FOR RWY 21C). SMA Y WAS ISSUED AN IMMEDIATE RIGHT TURN HDG 270 DEGS. THE TARGETS WERE MERGING ON RADAR. SMA X, FROM THE EYES OF THE TWR, APPEARED TO BE IN FRONT OF LTT X AND TURNING W. LTT X STARTED A CLB TO AVOID TFC. LTT X ELECTED TO CONTINUE THE APCH AND LAND RWY 21R. SMA Y WAS GIVEN A RIGHT 360 DEG TURN TO FINAL AND LANDED RWY 21R W/O FURTHER INCIDENCE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR GAVE EXPERIENCE LEVEL. NO SPECIFIC DISTANCE WAS MENTIONED ON NMAC, BUT TARGETS DID MERGE ON THE BRITE RADAR. TFC HAD BEEN GIVEN TO BOTH ACFT AND SMA HAD STATED THE SMT WAS IN SIGHT. RPTR FEELS THAT SMA HAD ANOTHER ACFT AND NOT THE SMT IN SIGHT. SMT DIDN'T SEE THE SMA UNTIL HE STARTED A TURN TO THE W, AND AT THAT TIME, SMT PULLED UP TO MISS THE SMA. LOCATION OF INCIDENT WAS ON FINAL APCH RWY 21R, APPROX 5 MI.
