What criminal punishment will a man get for killing his ex-girlfriend's family of five?

It is a very bad criminal case that the man killed his ex-girlfriend's family of five. This person has committed the crime of intentional homicide, so a person with such a bad plot should be sentenced to death and executed immediately. However, because the man was very ashamed after killing his ex-girlfriend's family of five, he later committed suicide by jumping off a building. As the man has died, he cannot be investigated for criminal responsibility. This man hurt his ex-girlfriend's family in order to get back at him. It's really cruel. This murder case happened in Fushi Street, Fushun County, Zigong City, and it was a murder case in a residential area. The 43-year-old Jiang Moumou's family of five died at home. The deceased included 43-year-old Jiang Moumou, Jiang Moumou's twin sister Jiang, Jiang Moumou's mother (67 years old) and Jiang's twin daughters 1 1 year old. Later, after investigation, 33-year-old Qiu Moumou was suspected of committing a major crime. On the second day after the incident, Qiu Moumou fell to his death in a hotel in Fushun County.

Qiu Moumou did not die on the spot after falling from the building. In the process of being taken to the hospital by ambulance, he revealed to the people around him the fact that he killed five people in the Jiang family. Some people say that Qiu Moumou killed Jiang Moumou's family because of emotional disputes, while others say that it was because of economic disputes. However, the police are still investigating the specific situation. Since both the suspect and the victim are dead, it is still difficult to obtain evidence.

If the murderer Qiu Moumou did not jump to his death, then he brutally killed all five ex-girlfriends, which was a very serious intentional homicide. If the crime of intentional homicide is serious, he shall be sentenced to fixed-term imprisonment of not less than 10, life imprisonment or death. Such a cruel modus operandi as Qiu Moumou should be sentenced to death for killing so many people. Now even if Qiu Moumou has committed suicide and apologized, his death will not repay the lives of these five people.
