Weld County communities mourn 2 tragedies in 2 days

FREDERICK, Colo. -- A community gathered outside a church Tuesday night to mourn the deaths of two men killed in a house explosion Monday as well as another man killed in a motorcycle crash Sunday.

The joint vigil was hosted at Rocky Mountain Christian Church in Frederick. The family of Grayson Wolff, who died in the motorcycle accident, had originally planned the vigil for Tuesday night.

After Monday's home explosion, they invited the Martinez family and friends to participate as well so everyone could grieve together.

"We believe in the power of prayer and tonight I know there are a lot of people praying for the Martinez family, everyone who knows Grayson Wolff and their family. Loss is hard. Unexpected loss is even harder," pastor Matthew Cote said.

On Monday, friends say Mark Martinez and his brother-in-law Joe Irwin were fixing a hot water heater in Mark Martinez's home when something catastrophic happened. On Tuesday, investigators pulled two bodies from the decimated home.

Erin Martinez, Mark's wife, was also home during the explosion. She was upstairs with one of their children. She was airlifted to a hospital in critical condition.

Mark Martinez was the town foreman and a certified plumber.

"Shock. Just shock. Disbelief. I am hurting real bad right now. These guys are amazing, great, great. Everyone here knows them. We all grew up together in this community," Robert Espindola said.

Erin Martinez is a chemistry and physics teacher at Mountain Range High School in Westminster.

"She is really beloved by students. Respected by her colleagues for her professionalism and what she does for kids," Adams 12 School District spokesman Joe Ferdani said.

Investigators are still working to determine what sparked the explosion. The couple has two children. They are doing OK.

A GoFundMe page has been set up to help the Martinez and Irwin families.
