Santa Paula police have a second suspect in custody in the tragic death of a mother killed by a stray bullet.

Police arrested Valente Tobias, whom they said is a Santa Paula gang member. They said Norma Elizalde died when rival gang members got into a fight outside her home last month.

Tobias was arrested while in the Ventura County Jail on unrelated charges. The first suspect, Mark Martinez, was arrested earlier this week.
