Police believe the suspect sexually assaulted three women in the neighborhood. They also believe he is responsible for 13 burglaries since March, taking computers, cash, jewelry or clothing.
Police describe the suspect as a Hispanic man, between 5 feet 7 inches and 5 feet 10 inches tall and weighing between 160 and 180 pounds. He is said to be in his mid 20s or 30s with a slim build, dark complexion and a mustache. One sketch released shows him without a mustache.
The suspect has entered homes through unlocked doors and windows. Police are cautioning people to keep windows and doors locked at night.
While women in the neighborhood say they still feel safe, they have taken precautions.
"I try not to worry about too much and go along with my life, but I can see how it's a little bit alarming," said Laura Hessenflow of Los Feliz.
