There will be a new mystery in 13 Reason's Why Season 3, and fans will surely try to solve the puzzle. After Netflix renewed the show for Season 4 ahead of the new installment's release, it will be the last and final bow that will answer all the lingering questions.

The biggest question today is who killed Bryce Walker (Justine Prentice)? The new season's trailer teased it would be the major plot of the show this time and not Tyler's (Devin Druid) failed school shooting attempt.

With Bryce's behavior, there are a lot of possible suspects. Many people hate him, and they may have the intent to end his life. So, here are the possible characters that may have killed Bryce in 13 Reason's Why Season 3, per ScreenRant.

Clay (Dylan Minnette) is the most definite contender when it comes to killing Bryce. He was the one who got tortured by Hannah's (Katherine Langford) tapes in Season 1 and fought justice for her in Season 2. Although there might be other reasons as to why Hannah took her own life, it couldn't be denied that a significant part of it was because Bryce raped her.

Another suspect is Jessica (Alisha Boe). Hannah could no longer avenge herself against Bryce, but Jessica could. Bryce also raped Jessica, but she didn't tell the truth until Justin (Brandon Flynn) gave his testimony.

Bryce only received a short sentence, and not everyone was happy about it, including Jessica. She might be able to move on and forget the trauma, but she would find it hard to do while Bryce was still around.

Tyler might also have the reason to kill Bryce in 13 Reasons Why Season 3. He is often a victim of Bryce's bullying in the previous two seasons. He was even the one who suggested to pin everything on Bryce during the trial, only that others didn't approve.

In the previous season, Tyler dealt with his anger issues after he got in trouble with his new friends. When he returned to school, he was beaten up and sexually assaulted by Bryce's friends. This ignited him to carry out a school shooting and might be the reason for his anger toward Bryce.

Meanwhile, Netflix renewed the show for the last and final season ahead of 13 Reasons Why Season 3 release. According to ComicBook, Season 4 is now in production although no official details about it are unveiled yet.

It will reportedly be about the high school graduation of all the primary cast members. On Aug. 23, fans are about to see 13 Reasons Why Season 3 on Netflix, while its fourth and final season may be out next year.
