Biography
Although he is never seen firing it, His weapon of choice was a Winchester Model 70. He accompanied the InGen group to the island only to be killed along with the rest of the group by Velociraptors. Later on, Nick Van Owen found Ajay's bag. Ajay's death led to Roland refusing a full-time position at InGen.
Ajay suggests to the other hunters that they should not to go into the long grass as it is where the Velociraptors'' are lurking. He is killed after he follows his group into the long grass, trying to convince them to return. His death is never actually seen, although you hear his screams. His death is later spoken of by Roland.
As a side note, one of The Lost World's deleted scenes featured the main characters (including Ajay) hang-gliding to get away from the Velociraptors. The group makes out of the tall grass and over a cliff to safety, only to be ambushed by Pteranodons. Ajay (or another balding bespectacled character) was supposed to be ripped apart by the winged predators, a scene so gruesome that Sarah had to look away.
Another deleted scene shows Ajay meeting Roland in a bar and convincing him to join Peter Ludlow's team on Isla Sorna.
