Embodiments monitor items corresponding to a vehicle. Embodiments determine a maximum speed of the vehicle. Embodiments determine a last known first geo-location of a first item, the first geo-location including a first location and corresponding first time and determines a last known second geo-location of a second item, the second geo-location including a second location and corresponding second time. Embodiments determine a reachability radius including a difference between the second time and the first time and multiplying the difference by the maximum speed. Embodiments determine a distance between the first location and the second location and when the distance is greater than the reachability radius, determine that the first item is detached from the second item.
