The LA Times seems to have taken a serious interest in the Mendiola story. It has another article today.

The article says that Giuliana and Giocanda were questioned by police. The Mendiolas apparently have an apartment in Seattle -- not clear if the daughters live there. The murder victim's last cell phone call was to the Seattle apartment, and his car was found in Seattle several weeks after his murder. But the girls "were quickly dismissed as suspects." The supervising detective said he didn't want to see Giuliana and Giocanda get hurt as a result of this case. (That might be impossible.)

The article also discusses the family's past behavior at basketball games. A couple days ago I linked to posts, like this one, from folks in the SoCal women's hoops community who have experience with the Mendiolas. Most are negative, but some have expressed support: "The Mendiola family was always incredibly kind to my daughter, who played El Toro basketball with both Gio and Giuli. Yes, the boys were loud and relentless, but despite what you might think of them, they loved the El Toro team and cheered the girls on no matter what."
