A passenger on a Southwest Airlines Co. flight died Tuesday after an engine broke apart at more than 30,000 feet, spraying metal pieces through the fuselage and forcing the crippled jet to make an emergency landing.

The passenger killed was Jennifer Riordan, who worked as a community-relations leader for Wells Fargo & Co. in New Mexico and was a married mother of two children, her sister-in-law, Marianne Riordan, said in an interview.
Witness reports, videos and preliminary information gathered by federal officials suggest the Boeing 737-700 suffered the most serious and rare type of engine problem, called an uncontained failure, in which rapidly spinning parts break off and end up penetrating the engine’s outer casing and front cover.
