This record documents arrests, charges and convictions reported by courts, law enforcement agencies and news organizations. Every statement is tied to a cited source with an archived copy. A charge is an accusation, not proof of guilt; a person charged is presumed innocent unless convicted. Solve the Case does not allege that this person committed any offense beyond what the cited records state, and this record is not a suggestion that the person is connected to any unsolved case. How records are built, corrected and removed.

Summary of the record

Diana Lumbrera was convicted of first-degree murder in Kansas in 1990 for smothering her 4-year-old son Jose Antonio Lumbrera to collect insurance proceeds.
