POMONA (CBSLA.com) – The uncle of slain North Park Elementary School teacher Karen Smith described her Tuesday as “gentle and soft-spoken and a quiet person.”

“There’s no one who would’ve been less deserving of this kind of thing than Karen was,” Henry Alexander told CBS2 Tuesday. “She was a person who was always doing what she was supposed to be doing all the time. She was always doing the right thing. So this is kind of an ultimate irony.”

“She was a very quiet, very conservative person,” Alexander said. “If you look in the dictionary for ‘good girl,’ there’s her picture. She was just the embodiment of reasonableness and conservatism godliness.”
