STS local controller described a failed coordination event when a jogger near the runway; reported to other tower personnel; went unnoticed/coordinated and traffic operations continued.

Narrative

Runways 14 and 19 were the active runways at the time and we were using visual approaches. I was local control. My traffic consisted of Air Carrier X on a straight in to Runway 14; a Cessna in right close traffic to Runway 14; a Bonanza and Cirrus in left traffic for Runway 14; and another Cessna holding short Runway 14 for departure. I scanned Runway 14 and cleared Air Carrier X to land. Once Air Carrier X touched down I watched his roll out to see which taxiway he would make and seeing he was going to the end of the runway; I told him to turn left at the end and contact ground. Then I issued a wake turbulence advisory to the landing Cessna for the arrived Air Carrier X and cleared him for touch and go. After that I cleared the departing Cessna for take off on Runway 14 without delay because the arriving Cessna was on right base to final. I sequenced the Bonanza to follow the landing Cessna and the Cirrus to follow the Bonanza. After the arriving Cessna did their touch and go and had just lifted off; I overheard Ground Control and the FLM (Front Line Manager) discussing a person being near Runway 14 on the west side (I would learn later that Air Carrier X had apparently informed Ground Control of this but the Controller did not inform me; the Local Controller; instead they informed the FLM who also failed to inform me) and after overhearing them talking I became alerted to a person who appeared to be jogging west of Runway 14. I issued a general cautionary advisory to the landing Cessna; Bonanza; and Cirrus. Because the Bonanza was on short final; cleared and committed to land Runway 14 and because I had observed the jogger was not on the runway but west of it in the grass; I did not try to send the Bonanza around as a late go around in my opinion would have been equally or more unsafe then allowing him to land. The Cirrus and Cessna I then changed to Runway 19 and proceed to coordinate with ground to allow airport personnel and law enforcement personal to cross Runway 14 and intercept and remove the jogger. Recommendation; I will work to develop a more intense scan so I will catch these anomalies sooner. Better communications between the tower team so that if these anomalies are noticed and communicated to the Local Controller right away.
