Narrative:
I was working local control at prescott tower. Runway 3 was the active runway, ground control coordinated a runway 29 departure (aircraft Y). The ground controller was then relieved by another controller, the first ground controller did not tell the relieving controller about the crossing (runway 29) being active. The new ground controller taxied aircraft X in to the ramp across runway 29 as I cleared aircraft Y on runway 29 for takeoff. The aircraft X taxiing to the ramp was through the intersection when the aircraft Y rolling runway 29 was about 750' from the intersection. Callback conversation with reporter revealed the following: reporter stated the aircraft involved were high wing small aircraft's. No operational error was filed. Although the ground controller taxied aircraft Y to runway 29, which made the runway active, did not inform the ground controller that aircraft Y was departing.

Title: ACFT X CROSSED RWY IN FRONT OF DEPARTING ACFT Y. LESS THAN STANDARD SEPARATION. SYSTEM ERROR.
Narrative: I WAS WORKING LCL CTL AT PRESCOTT TWR. RWY 3 WAS THE ACTIVE RWY, GND CTL COORDINATED A RWY 29 DEP (ACFT Y). THE GND CTLR WAS THEN RELIEVED BY ANOTHER CTLR, THE FIRST GND CTLR DID NOT TELL THE RELIEVING CTLR ABOUT THE XING (RWY 29) BEING ACTIVE. THE NEW GND CTLR TAXIED ACFT X IN TO THE RAMP ACROSS RWY 29 AS I CLRED ACFT Y ON RWY 29 FOR TKOF. THE ACFT X TAXIING TO THE RAMP WAS THROUGH THE INTXN WHEN THE ACFT Y ROLLING RWY 29 WAS ABOUT 750' FROM THE INTXN. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: REPORTER STATED THE ACFT INVOLVED WERE HIGH WING SMA'S. NO OPERATIONAL ERROR WAS FILED. ALTHOUGH THE GND CTLR TAXIED ACFT Y TO RWY 29, WHICH MADE THE RWY ACTIVE, DID NOT INFORM THE GND CTLR THAT ACFT Y WAS DEPARTING.
