When police responded to the museum, they spotted the pair running out of the building.
Police say the suspects appeared to have a motor boat waiting for them in Buffalo Bayou, which borders the museum.
They took off down the bayou, but when they spotted officers on the Shepherd Drive bridge, the suspects turned around and went in the opposite direction, according to Lt. Larry Crowson.

Officers were also staged on the West Loop feeder road bridge over the bayou, but before the suspects got that far, police say they hid with the boat somewhere near the Brenner s on the Bayou restaurant in a culvert.
