DREADFUL SUICIDE
The number of suicides which occur almost daily in California is alarming to contemplate. There must be something in the air, of some pre-disposing cause to bring about so many melancholy and sad bereavements. On Sunday
evening, the 3d inst., just previous to dusk, one of the native California residents of this place, LEANDRO OSUNA, terminated his earthly career by his own hands. The deceased had been laboring under a pulmonary affection
for a year or more, and his case appeared to be hopeless. At times, he gave way to sudden fits of insanity, and it is presumed that laboring under a temporary aberration of mind, he committed the fatal deed. He was in his
bed at the time, and his family in an adjoining room. A nephew of Mr. Osuna, having come to pay a visit, happened to bring a pistol along with him. The deceased asked permission to look at it, with a view, as he said to its examination. As soon as he was in possession of the instrument of death, he requested his nephew to step aside a few moments. He then bade "adios" to his family, and cocking the pistol (which was loaded) he presented it to his breast, pulled the trigger, the contents penetrating the body near the heart. He shortly afterwards expired. He was about thirty-seven years of age, and leaves an interesting family of a wife and four children to mourn his loss. Coroner Strauss held an inquest on his body, when the jury returned a verdict in accordance with the above facts. His body was interred the next day in the Old Mission burying ground near the windmill.

He was the son of the first Alcalde of San Diego, Juan Maria Osuna & his wife Maria Juliana Josefa Lopez Osuna.
