A small monkey was found dead at a North Texas zoo following a break-in by vandals over the weekend.
Gainesville police spokesman Sgt. Belva McClinton said Tuesday that authorities don't know what caused the death of the cotton-top tamarin at Frank Buck Zoo.
She says police have identified three juvenile suspects in the vandalism, but are still investigating and have made no arrests. The intruders broke in sometime after closing Friday at the zoo about 70 miles north of Dallas.
Zoo director Susan Kleven tells the Gainesville Daily Register that the vandalism included oil poured on all-terrain vehicles, a discharged fire extinguisher and damage to some exhibits. She says a turkey vulture had broken feathers.
Kleven says a necropsy will determine the monkey's cause of death.
