What is a summary and character analysis for John Steinbeck's "Flight"?

In John Steinbeck's short story "Flight," widow Mama Torres ekes out a living on a small California coastal farm with her three sons. She sends the oldest son, Pepe, on an errand in Monterey, trusting him for the first time to travel alone. Pepe has a bit to drink and knifes a man in a scuffle. When he returns home from the errand, his mother helps him pack as he flees from men whom he knows will come after him.
Pepe's pursuers catch up with him on the trail and shoot his horse. Pepe is wounded and gets away on foot but eventually loses his rifle. Ultimately, he is tracked by his pursuers' dogs, shot dead, and covered over by falling rock.
A character analysis of Pepe would focus on his short-lived rite of passage. He is able to only imperfectly finish the errand his mother sent him to complete. He says over and over again that he is a man, but he does not have the wisdom that comes with age and experience. Unfortunately, the mistake of knifing a man is an unforgiving one that he pays for with his life before he truly can become a man.
