Neighbor Bettie Jones, 55, also died after being shot 'accidentally', police said

LeGrier's father said in a 911 call that his son was holding a baseball bat

The Chicago police officer who shot and killed a teenager is planning to sue him and his family for assaulting him and causing emotional distress.

Officer Robert Rialmo responded to a domestic disturbance call at Quintonio LeGrier's home on December 26.

The 19-year-old died after suffering six gunshot wounds. The autopsy report showed four of them were located on the back of his body.

Rialmo now wants to sue LeGrier and his family on the grounds of assault and emotional distress, CBS Chicago reported.

Quintonio LeGrier, 19, died after he was shot six times by officer Robert Rialmo in December. Rialmo now plans to sue LeGrier and his family on the grounds that the teenager assaulted him and caused him 'emotional distress'

The LeGriers' attorney, Bill Foutris, told the network the planned lawsuit was 'desperate' and 'a baseless attempt to deflect attention from the fact Rialmo shot LeGrier four times in the back without justification'.

Audio recordings released earlier this month revealed LeGrier had called 911 three times the night of his shooting.

In his first call, he said there was an emergency and asked for a police officer to be sent to his home.

The dispatcher asked LeGrier to answer some questions and hung up when the teenager didn't.

After two other unsuccessful calls, LeGrier's father called 911 too and said his son had 'freaked out' and that he needed an officer.

'He's got a baseball bat in his hand right now,' the father said.

Rialmo showed up shortly after and shot the teenager.

Bettie Jones, 55, a neighbor, died after the same shooting after she was struck once in the chest.

Bettie Jones, 55 (left), who lived in the floor below, was also shot and killed that night. Police said her death was an accident. LeGrier (right) was carrying a baseball bat shortly before his death according to a 911 call made by his father

Police issued a statement in early January saying officers 'were confronted by a combative subject resulting in the discharging of the officer's weapon which fatally wounded two individuals'.

They said Jones was 'accidentally struck and tragically killed' and offered condolences.

LeGrier's father gave his version of events to the Chicago Sun-Times in December.

He heard a loud banging on his bedroom door at 4:15am and his son saying: 'You're not going to scare me.'

He said his son tried to break down the door but he kept him from doing it and called the police.

LeGrier's father said he called Jones, who lived in an apartment below, to warn her his son was 'a little irate' and tell her not to open the door unless the police were here.

He said Jones told him she had seen his son outside with a baseball bat.

He heard her yell: 'Whoa, whoa, whoa!' when the police arrived and was on his way down when he heard the gunshots.

He told the police he was LeGrier's father and held out his hands.

The Justice Department launched a federal civil rights investigation in December last year looking into use of force by the Chicago Police Department, which will examine racial and ethnic disparities.

The investigation was launched after the release of a police dashcam video showing officer Jason Van Dyke shooting black 17-year-old Laquan McDonald 16 times in 2014.

An audit conducted by Chicago Police showed that 80 per cent of the department's dashcams do not have functioning audio.
