Nothing is known about Matthew's life prior to or as the outbreak began aside from the fact that his mother died in child birth and he was adopted by Leah.
While discussing events related to losing their loved ones that broke them, Leah tells Daryl she had an adopted son whose mother - who was like a sister to Leah - died giving birth to him. She goes on to explain that, one night, when her group was attacked by a large herd, Matthew was bitten and that she didn't realize until they had run for miles and found an abandoned cabin. Matthew later either succumbed to the infection, or was put down out of mercy by Leah before he could turn, and was in turn buried in the backyard by his grieving adoptive mother.
- Killed By
- Zombies (Alive)
Matthew was bitten by a walker and subsequently died.
- Leah Shaw (Before Reanimation or Zombified)
Given that he was bitten by a walker, it is likely that Leah killed him before or after he reanimated.
This list shows the victims Matthew has killed:
- Possibly a few zombies
- "Find Me" (Flashback, Photograph)
- He is the only known member of the Reapers to be a child.
