A college student from the University of Iowa has been charged Wednesday after lying and covering his crime of cruelly shooting his parents and sister dead.

A complaint stated that Alexander Jackson, 20, concealed his crime by calling the police on Tuesday reporting that an unidentified masked man intruded into his family’s home in Cedar Rapids and shot him and his father, Fox News reported.

The bodies of Jan Jackson, 61, Melissa Jackson, 68, and Sabrina Jackson, 19, were discovered lifeless with gunshot wounds in different rooms in their home as authorities arrived on the scene.

Alexander was rushed to a hospital to get his foot treated from a gunshot wound.

Suspicions were raised when Cedar Rapids police did not find any signs of forced entry or burglary at the property.

Law enforcement also retrieved a .22 caliber semi-automatic rifle, which was alleged to have been used in the fatal shooting of the victims, from the home.

Jackson was later taken into custody after being treated at the hospital. He is currently being held at the county jail while awaiting trial for charges of first-degree with a $1-million bail bond for each of the slain victims.

The Gazette reported that Assistant Linn County Attorney Ryan Decker described the incident as "a horrendous murder."

"This was more than just a murder – it was an execution of the defendant’s mother, father, and sister," Decker said. "Furthermore, the defendant’s concocted story of a phantom burglar shows the defendant acted out of malice and calculated intent to get away with these murders."

According to the complaint, Jackson first called the police and reported that he woke up to the loud gunfire from a masked man and was shot together with his father.

He denied shooting his family members but later admitted that his father had recently told him he needed to find a job or move out of the home.

The Cedar Rapids Police Department tagged this case as the city’s first triple homicide in nearly 40 years.

A vigil was held on Wednesday night at Kennedy High School, where Sabrina and Alexander Jackson attended high school, the Daily Iowan noted.

The young Jackson son reportedly had no criminal history as neighbors who spoke with the Gazette said that “they were good neighbors and nice people.”
