The man was identified as Salvador Martinez, 28, of Maywood. Authorities believe Martinez broke into a home in the area of Slauson and Maywood avenues Sunday and raped the victim.
The crime happened between midnight and 4 a.m., police said. The victim was alone in her home at the time of the attack.
Detectives said Martinez's fingerprints link him to the brutal attack. Authorities also released photos of tattoos Martinez has that can help the public identify him.
The rape comes not long after a series of break-ins and other sexual assaults in the area. Other incidents involve two women being groped, including a 13-year-old girl.
Authorities have not been able to say if Martinez is tied to those crimes, but they believe he could be.
"At this time we have not been able to definitively tie him to the crimes, but there are a lot of similarities that we're working on. We think within time we may be able to tie him to those other crimes," Lt. Robert Peacock said.
