Innocent? Hardly. From the article:
Deaton [Flores' attorney Ryan Deaton], however, said Basoria decided when she was four months pregnant that she wanted an abortion. When she couldn't get one, Flores hesitantly agreed to press his 175-pound frame on her belly.
"He's out having fun with his friends. He's a senior," Deaton said. "She's getting bigger and bigger and fatter and fatter and she's very jealous."
Deaton acknowledges Flores and Basoria argued in the hours before she miscarried about him arriving home late, and Flores hit her.
"The reason I didn't want the baby's cause of my school," Flores wrote. "But what now!! I am not in school! I am in jail!!!"
I cannot think of likely circumstances under which it would be permissible to strike a pregnant woman. Can you?
That's not murder. She did plenty to induce the miscarriage on her own, one blow shouldn't do it.
