1995
Lois Heather Mack (born October 1995) is an American heiress convicted of murdering her mother, Sheila von Wiese, while on vacation in Bali, Indonesia, in August 2014.
The murder was widely publicized internationally because Mack and her boyfriend stuffed von Wiese-Mack's body in a suitcase.
She was sentenced to 10 years, of which she served seven.
However, in 2021 on her arrival to United States, Mack was arrested on conspiracy and obstruction charges.
In June 2023, Mack pleaded guilty to one count of conspiring to kill a U.S. national, and was later sentenced in January, 2024 to 26 years in prison.
2001
The Macks went on a Royal Caribbean Mediterranean cruise in 2001.
During the trip, James L. Mack suffered a foot injury, for which he did not receive adequate medical treatment from the ship's doctor, resulting in partial paralysis.
He filed suit against Royal Caribbean, saying that he was partly paralyzed, and had to urinate in a bottle, but this case took many years to resolve.
A settlement in the 2001 lawsuit was reached in 2011.
After legal fees, $340,667 was awarded to Sheila Mack, and $500,000 to the estate of James Mack.
Despite the existence of a will dated 5 days prior to James L. Mack's death, willing his entire estate to Heather Mack, the $500,000 was awarded to Sheila Mack by a judge in Cook County, Illinois.
No transcript for the case is available.
2004
Mack and her mother reportedly had a contentious relationship, with police reporting that they'd made 86 visits to the home between 2004 and 2013.
In 2004, police were called to the Mack residence over claims that the children from James' previous relationships were denied access to their father by Heather's mother who would turn off the lights and pretend not to be home.
It is reported that the police were called to the Mack home on 86 occasions on theft and domestic violence reports cases between January 2004 and June 2013 all relating to domestic incidents between mother and daughter.
2006
In 2006, the Macks went on a vacation to Greece.
During the trip, James L. Mack died in his hotel from a pulmonary embolism, on August 6.
2010
In January 2010, Heather punched her mother's broken ankle.
She was also accused of stealing $1000.
Heather attended Oak Park and River Forest High School from 2010-2014.
While a senior at Oak Park, Heather began dating Tommy Schaefer, an unemployed rapper also known as Tommy EXX.
Heather's mother did not approve of the relationship and so she sold their house and moved Heather and herself to the Gold Coast neighborhood of Chicago.
Despite this, Heather became pregnant by Tommy.
According to her lawyer, Heather had had two abortions under her mother's control and her mother was seeking to obtain a power of attorney over her daughter to enforce the third abortion, at the time that Sheila booked their final trip to Bali, where she was still waiting for blood work to find out if Heather was really pregnant.
2011
In February 2011, Heather broke her mother's arm, and then removed the phone cord to prevent her mother from calling 911.
In July 2011, Heather again threatened her mother.
2012
In November 2012, she bit her mother, leaving a bruise, but her mother refused to allow police to photograph it.
2014
In August 2014, Sheila and Heather arrived at the St. Regis Hotel in Nusa Dua, Bali, where they had flown first class.
Heather stole her mother's credit card and booked a business class flight to Bali for her boyfriend Tommy.
Tommy claimed that he had gone to Bali to tell Sheila about Heather's pregnancy, but emails later released showed that this was a lie.
On the night of August 7, 2014, security camera video at the St. Regis showed Sheila having an argument with Schaefer in the hotel lobby.
Shortly after, Tommy Schaeffer killed Sheila with a metallic blunt object in the room, which then led to Heather and Tommy stuffing the body of Sheila Von Wiese Mack into a suitcase.
The two then put the suitcase with the body into the trunk of a cab outside the St Regis.
After the couple did not return, a security guard found blood outside the suitcase and advised the cab driver to go to the police station.
After police found the body inside the suitcase, both Mack and Schaeffer were arrested at a nearby motel.
The couple told police that Sheila was killed by robbers, but they were able to escape
On August 15, 2014, both Mack and Schaeffer were designated as prisoners.
On August 20, a urine test confirmed that Mack was pregnant, which was initially thought to be a ruse for her to be sent home.
