Investigators are searching for a motive in the mass shooting at a Texas church that left 26 people dead and 20 wounded  Sunday’s massacre at the First Baptist Church of Sutherland Springs was the deadliest church shooting in modern U.S. history. Investigators said the victims ranged in age from 5 to 72 years old, with injuries ranging from minor to “very severe.” The gunman was identified as 26-year-old Devin Patrick Kelley. He lived in a suburb of San Antonio and didn’t appear to be linked to organized terrorist groups, a U.S. official told The Associated Press. A possible motive was unclear. The official said investigators were looking at social media posts Kelley may have made in the days before Sunday’s attack, including one that appeared to show a semiautomatic weapon. Witnesses say the gun was dressed in tactical gear when he opened fire on the church. Kelley was confronted by an armed nearby resident who chased after him. He was later found dead, roughly five miles away. It’s unclear whether Kelley was killed by police or the armed resident, or from a self-inflicted gunshot wound.

President Trump said the mass shooting was indicative of a mental health problem, not gun laws in the United States … “Mental health is your problem here,” Trump said. “This isn’t a guns situation. This is a mental health problem at the highest level. It’s a very, very sad event.” The president added that “based on preliminary reports” the shooter was “a very deranged individual.” Some Democrats have already politicized Sunday’s tragedy and called for more gun control. Former President Obama, former Vice President Joe Biden and Sens. Bob Casey Jr., Dick Durbin, and Kamala Harris were among the Democrats who urged action in response to the deadly shooting.
