Daniel Koch, 33
Daniel Edward Koch, 33, a white man, was stabbed in Limekiln Canyon Park in Porter Ranch on Sunday, Aug. 26, and died at 12:15 p.m. He had been arguing with two men, and one pulled a knife and stabbed him. An unknown passerby spotted his body, called 911, and disappeared.
Later, one suspect was arrested: Quinn Marez, 18, of mixed white and Latino descent. The quarrel, investigators said, had to do with name-calling.
Update: One more suspect, 18-year-old Justin Thalheimer, a white youth, was arrested in Santa Barbara May 6. Credit goes to LAPD Devonshire Dets. John Doerbecker and Mike Fesperman for this cleared case.



I live right near the murder scene. It's kind of scary that it would happen in a nice quiet neighborhood.

What was a 33 year old man doing with teenagers? And if there are other teens out there that knew him I wonder what they would have to say about this person?
