Who Killed Nadal?

This story is a sequel of the story Uncovering the Nadal’s story  so read that story first if you haven't read that. Now enjoy the part 3 of it :)

On his way to find the killer, Alex meets Emma, his high school friend. They met after a decade, and as they met, Alex felt a distinctive charm on her face. He was amazed. Alex had never encountered this kind of feeling before. He knew that she was also a common friend of Nadal, so he told the story to Emma, and she was shocked after hearing about the death of Nadal.

She asked Alex, “What was the cause?”

Alex said, “He was murdered.”

“Murdered?” Emma said in a loud voice. “Who’s the killer?”

Alex replied, “I’m still finding the clues to reach the freaking killer.”

Emma asked, “Can I join you?”

Alex saw and thought for a moment and said, “Yes.”

Emma had a wide smile on her face. Now, both Alex and Emma were finding clues day and night, and there indeed wasn’t just one clue that the murderer could have left. But days passed, and there was no clue.

But one day, Alex met Mike, a person who was present during the time of the accident. He told him that Nadal’s car was hit by a distinct red Lamborghini. While Mike didn’t remember the number, he managed to see a tiger sticker on the rear windshield of the car. This was a major clue for finding the killer.

From the next morning, Alex and Emma went to find the red Lamborghini. They did this for a whole day while crossing the bridge, but there was no clue. But the next day, when he was crossing the bridge, he found the same car with the same tiger logo on the rear windshield parked near the pavement. To share his excitement, he called Emma, saying that this time they could have caught the killer.

This was not a brand new car. The owner of the car said he bought it a few days back. “So this means the killer sold the car and misguided us to distract us,” Emma said.

“Yes, this could be the case,” Alex replied. But Alex was not going to sit idle, even though he knew it was difficult. He was focused, and he knew that with Emma, he would find the murderer.

And as the days passed with no clue, he was curious, and he went out to ask the previous owner of the Lamborghini. This could be an amazing idea.
