Drunk driver, 66, appears in court with a cast after smashing into boating club and killing two kids celebrating at birthday party in Michigan

The drunk driver charged with the second-degree murder of two children appeared in court Tuesday with a cast on her right arm.

Marshella Chidester, 66, has been accused of second-degree murder. She allegedly drove her SUV into the wall of Swan Creek Boat Club where a child's birthday party was being held on Saturday.

Lana, eight, and Zayn, five, both died in the wreck in Berlin Township in Michigan, while their mother, Mariah Dodds and elder brother, Jayden, are fighting for their lives.

When she entered the courtroom Tuesday, the livestream showed Chidester enter with a cast on her right arm, seemingly indicating that she suffered an injury during the incident.

The suspect has been detained since the crash. The judge granted her bond at the $1.5 million that the prosecution had asked for, at the request of some of the victims' families.

Surveillance footage showed the suspected drunk driver swerving erratically before crashing into a boat club hosting the children's party, which injured or killed a total of 15 

Prosecutor Jeff Yorkey informed the court that Chidester had a history of substance misuse, which her friends and family had confirmed, in support of the $1.5 million bond.

Bill Colovos, the defense lawyer, requested that the judge set Chidester's bond at $100,000.  He claimed that she has suffered from 'epileptic-type seizures' in her legs' since November. He also claimed she had only consumed a bowl of chili and a glass of wine four hours prior to the collision.

'This is not a monster,' Colovos said. 'It's horrible what happened, but there are some things we don't have control over.' 

Chidester's lawyer also pointed out that she does not have a history of reckless driving or traffic tickets.

Yorkey argued that Chidester showed no signs of having a seizure before the crash and that her blood alcohol level was 'significantly over the legal limit.'

If the accused pays her bond, she will be forced to give up her passport, alcohol, wear a tether, and not drive.

Chidester, who The Detroit News discovered was the former commodore of the boat club, is scheduled to appear in a probable cause conference scheduled for April 30 followed by a May 6 preliminary examination.

The children's aunt, Raquel Smouthers, testified in court. She said she was at the party when Chidester killed her niece and nephew.

'They were sitting at that table eating, and this woman crashed her car through this building destroying all of our lives,' a nearly inconsolable Smouthers said. 'Nobody should ever have to go to a birthday party thinking that they're gonna die.'

Dodds is suing Chidester and the tavern she allegedly drank at before getting back into her car, the law firm representing Dodds told AP News.

She sustained broken ribs, a collapsed lung, and cuts and bruises while her son broke his legs, some of his ribs, and fractured his skull

A GoFundMe has been set up to help cover funeral expenses for the children.

A huge first responder presence raced to the scene just after 3pm, where Goodnough said it was 'extremely chaotic' with 'high level of emotions.'

One child was reportedly pinned under the vehicle as it flew through the building, while the brother and sister who lost their lives were tragically pronounced dead at the scene.

Helicopters and ambulances took nine victims to nearby hospitals, who were listed as being in life-threatening condition.

Further victims were also taken to hospital in cars, Goodnough said.
