The husband of a teacher slain in Tuesday's shooting in Ulvade, Texas, suffered a fatal heart attack Thursday.

Joe Garcia was the husband of Irma Garcia, one of the two teachers murdered in Salvador Ramos' attack on Robb Elementary School Tuesday, according to FOX San Antonio reporter Ernie Zuniga. Joe and Irma leave behind four children.

Several Twitter and GoFundMe accounts also stated that Garcia had died due to "grief" or a medical emergency Thursday.

Garcia's death comes two days after Ramos' assault on the elementary school.
