The deadly elementary school shooting in Ulvade, Texas has claimed another victim -- the husband of one of the teachers killed.
He just died of a heart attack.
Joe Garcia and his wife, 4th-grade teacher Irma Garcia, had been married for 24 years and had four children.
Irma Garcia was one of two teachers slain during Tuesday's attack, along with 19 students.
A relative tweeted Thursday that Joe Garcia had "passed away due to grief".
Another has started a GoFundMe for the family, writing "I truly believe Joe died of a broken heart".
