Tonka was last seen at the now-defunct chimpanzee breeding facility Missouri Primate Foundation (MPF).
In 2017 – a decade after they had starred together – Angus-born Cumming wrote to the MPF to say he had heard the animal was living in a cages.

Chimps were bred at the location and then rented out for movies and parties or sold to private owners.
The animal cruelty charity PETA has put up its own $10,000 reward for information about Tonka’s whereabouts.
“During the months we filmed together, baby Tonka and I became good friends, playing and grooming each other and just generally larking about,” Cumming said in a statement. “It’s horrible to think he mightbe in a cage in a dark basement somewhere or have met some other fate, so I’m appealing to whoever knows what has become of him to please come forward claim the reward.”
PETA originally sued the MPF over the living conditions and claimed animals “had been warehoused in often filthy, virtually barren enclosures.”
It obtained permission to move Tonka and six other chimpanzees to an accredited sanctuary, but Tonka was missing when PETA arrived to make the transfer in July 2021.
In a statement, PETA said: “The Foundation owner claimed that Tonka had died but told various stories that didn’t add up leaving PETA and Cumming to try to determine his whereabouts or perhaps his final resting place.”
It continues: ““If you know where Cumming’s former co-star may have been shipped, sold or hidden away, PETA wants to hear from you.
