Weird news - A girl in the US being treated for eating soap multiple times a week

There are a number of people in the world who eat very strange things, such as the performers who come on TV who eat things such as tube lights, etc. And it is a normal concept in books where children who use abusive language or swear words are told to wash their mouth out by soap by their parents. The taste of soap must not be very nice, which is one of the reasons why the washing out of the mouth by soap must be encouraged.
So, how is that a normal girl eats soap 5 days a week, and which is now being treated by doctors (she also apparently eats washing powder, with a funny reaction being that her body must be very clean with all the soap and washing powder that she is eating) (link to article):

Tempestt Henderson, from Florida, eats up to five bars of soap a week and washing powder as well, the Daily Mail reported here. According to doctors, the toxic compulsion is a rare medical condition, PICA, which causes an appetite for substances that are largely non-nutritive.
People suffering form PICA have been known to compulsively eat metal, coins, chalk, batteries and toothbrushes. It can often be caused by a mineral deficiency, which explains why pregnant women often crave eating coal when needing iron. The doctor gave Tempestt intensive Cognitive-behavioural therapy (CBT), to give her replacement thoughts that will prevent her from compulsively reaching for soap.

Weird news - Maid has it as her mission to spread AIDS to all, through unprotected sex

Getting AIDS can cause a huge amount of emotional turmoil to the people afflicted with it. Earlier, getting AIDS was a certain death sentence, but now, with a number of medicines available, it is possible to live a healthy life for long periods of time. However, at the same time, there are a lot of laws in place that criminalize the wilful passing on of AIDS to other people, so passing on of the virus from one to another is a crime if done without the knowledge of the other person.
But, if a person has been given the virus by somebody else, it can cause a huge amount of anger and lead to a desire for revenge, which seems to have been the case here, where a lady was given the AIDS virus by her husband, and in her quest for revenge, she spread it to a number of other people (link to article):

A doctor treating HIV-positive patients has claimed that one of his patients has indulged in sexual relations with more than 100 partners "to take revenge" for her condition. While counselling her, the doctor learnt that she not only has multiple partners, but hunts for them with a vengeance to spread the virus she contracted through her husband.
"She was brought to us by her sister, who herself is HIV positive," said Gilada. "We found out that she had learnt of her husband's HIV-positive status in 2005, and that he had transmitted the disease to her as well. Although she divorced him, she couldn't come to terms with the fact that he had knowingly passed on the virus to her," he said.
Gilada said that during the counselling sessions, the woman, who works as a maid, claimed she has had more than 300 sexual encounters with 100 men over the past three years. "She admitted to frequent encounters with men ranging from her employers and their relatives, to the liftman and students - all of whom have had unprotected sex with her," said Gilada.

Weird news - Burglars rob a house, kill the witnesses (goldfish)

It is one of the most common conceptions, that goldfish have one of the shortest memories of all animals, with the memory level supposed to be that of a second. This is apparently a misconception, with the scientific belief being that goldfish can remember things for 3 months. However, when you combine this with the strongly held belief by some burglars that they need to get rid of all witnesses, the consequences were tragic for the goldfish.
Some teenagers robbed a house, and being young and enthusiastic, and having probably seen too many episodes of CSI, they were worried about being identified and caught, and hence decided to eliminate any possible witnesses to the crime, which in this case, were only some poor goldfish in the tank (link to article):

An Illinois teenager is facing residential burglary and cruelty to animals raps after killing a trio of potential witnesses to an Arlington Heights burglary - three goldfish. On 24 January, the unnamed 16-year-old and two accomplices, aged 15 and 17, targeted an apartment in a block which had been evacuated following a fire on 19 January. Police say they "pried open a door and stole a video game system, CD player, 30 video games, 30 DVDs, a BB gun, jewelry and a safe".
When the residents returned, they discovered "hot sauce, mustard, ketchup and spices had been poured into their fish tank and three goldfish floating at the top", the local Daily Herald reports.
