Narrative:
Vectoring the beech jet to follow the lear. The lear had just turned base on a visual approach clearance following a B727. I issued traffic for the beech jet to follow, the lear at 1 O'clock position 4 mi on right base. The beech jet reported the lear in sight and was instructed to follow the lear and given their visual approach. What I didn't know at the time was that the beech jet had spotted the B727 on 2 mi final and not the lear on right base. Therefore, when the beech jet turned in to follow, what he thought was the lear, he actually turned very close in front of the lear. When I noticed the beech jet turning in sooner than I thought was normal, I asked the beech jet 'verify you have the lear ahead and to the left in sight.' again the beech jet replied affirmative, but by then all the beech jet could do was turn final about 1 mi in front of the lear.

Title: BEECH JET IS ON VECTOR BY GSO APCH CTLR TO FOLLOW AN LR60 #2 ON BASE BEHIND A B727. THE BEECH JET MISTAKENLY FOLLOWS THE B727 AND ENDS UP 1 MI IN FRONT OF THE LR60.
Narrative: VECTORING THE BEECH JET TO FOLLOW THE LEAR. THE LEAR HAD JUST TURNED BASE ON A VISUAL APCH CLRNC FOLLOWING A B727. I ISSUED TFC FOR THE BEECH JET TO FOLLOW, THE LEAR AT 1 O'CLOCK POS 4 MI ON R BASE. THE BEECH JET RPTED THE LEAR IN SIGHT AND WAS INSTRUCTED TO FOLLOW THE LEAR AND GIVEN THEIR VISUAL APCH. WHAT I DIDN'T KNOW AT THE TIME WAS THAT THE BEECH JET HAD SPOTTED THE B727 ON 2 MI FINAL AND NOT THE LEAR ON R BASE. THEREFORE, WHEN THE BEECH JET TURNED IN TO FOLLOW, WHAT HE THOUGHT WAS THE LEAR, HE ACTUALLY TURNED VERY CLOSE IN FRONT OF THE LEAR. WHEN I NOTICED THE BEECH JET TURNING IN SOONER THAN I THOUGHT WAS NORMAL, I ASKED THE BEECH JET 'VERIFY YOU HAVE THE LEAR AHEAD AND TO THE L IN SIGHT.' AGAIN THE BEECH JET REPLIED AFFIRMATIVE, BUT BY THEN ALL THE BEECH JET COULD DO WAS TURN FINAL ABOUT 1 MI IN FRONT OF THE LEAR.
