The Spanish lady has some serious mental health issues in the past. My hunch tells me the Church didn't appreciate her donation and contribution. It's not a legitimate church where anyone with a bad rep can turn his/her life around. It's a "Mega-Church" where all these brainless people giving away tons of money to this false pastor, Joel Osteen. My theories: (1) she goes up to the preacher and got a hand on her shoulder saying she's forgiven by God and she's cleansed. (2) Several days later, she want to say "thanks" and send "donation" to that megachurch. (3) Months go by, she suffered somewhat "schizophrenia". She doesn't feel anything changed. (4) One day she heard from someone or read some news saying U.S. ain't Christian enough. She has been lied by our government they send trillions of our tax dollars to Israel for wars instead of using these money to help our Americans escape from poverty. She got mad and purchased a gun. So she went on vengenceful mode. Pretty much similar to the German mother went to the court and shot the rapist who killed her seven month daughter.
