Police arrested 33-year-old Edwin Holt Thursday for the murder of Alex Walls in Desert Hot Springs in July.
Holt is accused of stabbing and killing Walls at a home in the 66000 block of Fifth Street in Desert Hot Springs on July 18. Walls died at Desert Regional Medical Center. Investigators said the whole thing was caught on home surveillance video, but didn't say if that helped lead to Holt's arrest.
According to authorities, Holt was already in custody on an unrelated charge when they arrested him in connection with the murder case.
Holt is being held at the jail in Banning.
