I was thinking Hatari and Delano could arrive when Sanders has already left.
Enraged by the idea of someone trying to hurt his cubs, Muroki immediately forgot all of his reservations and hesitations as he tried to get to Sanders and attack him, only to be blocked by the Chief of Police and subdued rather easily. He barely managed to force the attacking lion off of him and stand up, only to get slammed in the face by his paw and find himself rolling over the edge of the gorge as he desperately managed to cling onto the sharp edge and prevent himself from falling.
He could sense that he had enough strength to pull himself up to safety but, as the Chief approached him with that disturbing grin of his, it finally dawned on Delano's brother that there was no escape. He was going to die. He was never going to see Umeme or Delano or his cubs again... There was nothing he could do to protect his son and daughter and that was the worst feeling he's ever experienced in his entire life.
"I know what you're thinking..." said the Chief apathetically as Delano's brother shut his eyes tightly in both fear and shame. Something was telling him that the crazy lion could read him like an open book at the moment.
"That really does sound horrible, but I'm sure you'll be able to live with it. For the short remainder of your life, that is." Without as much as a slight consideration, he threw his helpless victim into the gorge, not even bothering to watch him fall down as he turned around.
"It would be much more fitting for you to kill Delano after he sees his precious little son dead, you know." he pointed out.
"So why don't you run along and I'll join you soon?" Grinning, he looked at his 2nd in command, who had a horrified and disgusted look on his.
"Don't worry, Lin, I haven't forgotten about you." Not waiting to see whether Lin's leg still hurt that much or not, he threw him into the gorge as well as Sanders took his leave.

Hatari also came to a halt after a rather brief moment of looking around, staring at Delano with a slightly confused look.
"Not really..." he admitted, also looking down towards the water. They were quite close to that long, treacherous gorge that was a part of the border... Whatever sound Delano might have heard could have easily echoed through the gorge.
If it was real and Muroki's brother wasn't sure as to whether it was just in his imagination, chances were that it was pretty far off from their current location. That gorge really was big...
"We could go and investigate." said the former member of the underworld. He doubted Delano has forgotten how Sanders had tried to kill them and Kato there before. Maybe he was wondering about in that area, seeing how there seemed to be no trace of anyone where they were?
