Statement from Faultless Healthcare Linen:

We have learned that our third employee, Clifford Lee, injured in the reported Loy-Lange boiler explosion, has died of his injuries. We understand that he was a friend of Tonya Gonzalez-Suarez and Christopher Watkins, who were married to each other and also died of their injuries. For each of the three, it was their first day of work at the plant.

We mourn this terrible loss with their families and are grateful for the thoughtful and generous support offered to these families by so many in this community.

The Sons & Daughters of Soulard, a group of charitable- and community-minded business leaders based in Soulard, were among the first to offer their aid and graciously took the lead in setting up a relief fund to benefit the families. Their GoFundMe page can be found at https://www.gofundme.com/faultless-explosion-victims-fund. We understand some of the family members may have set up their own relief fund pages which are another resource for those wanting to show their support.

We also appreciate the many kindnesses shown to our company in these last days by city officials, business and community leaders as well as many individuals.
