It looks like Daniel’s brother is Martin Jr. , and the available reporting doesn’t show anything bad happening to him. The family’s other business, MJD Pressure Washing, includes Daniel and his older brother Martin Jr., and it’s described as continuing to donate services as of the latest coverage.

What the reports say

  • M&D Lawn Care is still active, with Daniel and his father Martin Hernandez doing free lawn work for people in need.
  • The Hernandez family’s pressure-washing business also includes Daniel’s older brother Martin Jr..
  • I didn’t find any credible report saying Martin Jr. disappeared, died, or had a major public incident.

Why people are asking

A lot of recent posts and videos seem to be driven by rumor-heavy titles like “what happened to M&D Lawn Care,” but the reliable coverage points to a much simpler story: the business grew, got attention online, and kept going.

So the most accurate answer is: Daniel’s brother appears to be fine and still part of the family business story. The “what happened” chatter seems to be internet speculation rather than evidence of a real crisis.

TL;DR: Daniel’s brother is Martin Jr., and nothing in the reliable coverage suggests anything serious happened to him.
