UPDATE: Officials have released the name of the man whose head, feet and hands were found in Bronson Canyon this week. According to the Los Angeles Times, the man has been identified as Hervey Medellin, a 66-year-old former Mexicana Airlines employee. Police have not identified any suspects in connection with the case.

The victim of the gruesome murder mystery in the heart of Hollywood's most historical location has been identified.

The head -- which was discovered in Bronson Canyon on Tuesday - finally has a name but the Los Angeles Police Department have not yet released it, reported CBS affiliate KCAL.

Detectives served a warrant on Thursday night at a Hollywood apartment as part of the investigation, and while no arrests were made, a car was towed from the property and neighbors were asked how often the trash was taken away.

A "person of interest" is being detained in Los Angeles in connection with the 55 arson fires set between Friday night and 1:30 am Monday.

The Los Angeles Police Department has not yet identified the man but he is the same person seen on surveillance tape cops released Sunday night as they appealed to the public for help in finding the arsonist.

He is from Germany and was battling the U.S. government over the immigration status of a relative, sources have told The Los Angeles Times, and was driving a vehicle with Canadian license plates when he was detained early Monday morning.

Emphasizing that their investigation is ongoing, the Los Angeles Fire Department said in a statement it is "too early to speculate if this person is responsible for the spree of arson fires."

The two new suspects in the vicious beating of San Francisco Giants fan Bryan Stow at Dodgers Stadium will make their first court appearance Monday in Los Angeles.

Louie Sanchez, 29, and Marvin Norwood, 30, are scheduled to appear in a Los Angeles Superior Court for arraignment on one count each of mayhem, assault by means likely to produce great bodily injury and battery with serious bodily injury; each man is being held on $500,000 bail.

The criminal complaint charging the men alleges that each inflicted great bodily injury on Stow, "causing him to become comatose due to brain injury and to suffer paralysis." The mayhem count alleged that they "did cut and disable the tongue, and put out an eye."

Many fans believe she only made it to the finals because of highly organized voting on the part of supporters of her mother, Sarah Palin.  But whether Bristol or one of her competitors -- Jennifer or Kyle -- was the intended target of the scare letter, law enforcement isn't saying.
