*UPD* #LASD Homicide Responded to Stabbing Death Investigation, 3100 blk N. Marengo Ave, #Altadena

About 2:45PM, Monday, March 22, 2021, Alta Dena deputies responded to the 3100 block of N. Marengo Avenue in Alta Dena regarding a possible kidnapping in progress.

When deputies arrived, they found a deceased male Black adult in the driveway of the location, who had been stabbed several times. They checked the inside of the location and found a deceased female Black adult inside the residence.

During the investigation, detectives learned that the female victim was conducting a Zoom call with a colleague, when the attack on the male occurred. The Zoom caller witnessed the attack on both the male and female and called 911 to report the crime.

Investigators learned a vehicle was missing from the residence. During the investigation, a male Black adult returned to the location driving one of the victim’s vehicles and identified himself as a resident of the home. The male, Robert Cotton (32), was detained and has since been booked for two counts of murder.

There is no additional information available at this time.
