The lead investigator in the murder case against a 40-year-old El Centro man accused of fatally stabbing Edward De La Cruz, 19, testified Tuesday.
El Centro police Detective Angie Cuevas is the investigating officer in the case against Salvador Serrato.
Serrato's attorney, Eduardo Rivera of Calexico, asked Cuevas during cross-examination if police took any samples of blood found on the scene or clothing of those involved in the altercation. She said they didn't.
Rivera is attempting to establish that Serrato was the victim and that De La Cruz punched him with an object three times on the face before the stabbing last summer.
