A man who has been called Teardrop Rapist has been attacking women in L.A. since 1996.

The last attack that we know of was reported one year ago this month. But police still fear he's active, and so this week the LAPD, the FBI and the city of L.A. announced that the reward for information leading to his arrest has doubled to $100,000:

The LAPD says he's behind 35 attacks between 1996 and last year, including 3 on the L.A. Sheriff's Department's turf.

In fact, a day after the department announced a reward of $50,000 in June, 2012, it revealed that he had attacked a victim only days before, on June 15, just south of downtown.

This is how the department described a November, 2011 attack by the gangster-looking serial rapist with a teardrop tattoo under one of his eyes this way:

… A 15-year-old female Hispanic walking in the area of Adams Boulevard and Normandie Avenue was approached by a male who asked her for directions. He then produced a handgun and forced her to walk a short distance to a yard where he sexually assaulted her.

That's pretty much his M.O., investigators say. He likes to attack in the morning, often between the hours of 5 and 8 a.m. His territory includes core, central neighborhoods from South L.A. to Koreatown. The LAPD:

The suspect typically approaches women who are alone on their way to school or work or who are waiting at a bus stop, between the hours of 5:15 a.m. and 8a.m. The suspect converses with the victim and then threatens to kill the victim with a handgun or knife. The suspect forces the victim from the sidewalk to a secondary location, where he sexually assaults her.

Detectives believe the suspect is in his 40s or early 50s, 5 feet 2 to 5 feet 6 inches, and 130 to 170 pounds. He usually sports a mustache. He might have tried to have his teardrop tat removed, cops say.

He has been partial to dark hooded sweatshirts, baseball caps, beanies and bandanas, police say.

If you think you know who it is and you want to make six figures, here's your chance. Call police at 877-527-3247.
