NEW YORK — What happens next after a Staten Island grand jury's decision not to indict Officer Daniel Pantaleo in the chokehold death of Eric Garner:

FEDERAL CIVIL-RIGHTS PROBE:

Attorney General Eric Holder announced Wednesday the Justice Department would launch a criminal civil-rights investigation into Garner's death. U.S. Attorney Loretta Lynch, who has jurisdiction over Staten Island, will oversee the probe. President Barack Obama recently named her to succeed Holder as attorney general.

Lynch has experience with police brutality cases; she was one of the attorneys who prosecuted New York officers in the 1997 broom-handle assault on Abner Louima. "Since the death of Eric Garner in July, our office has monitored this case closely," she said in a statement. "The investigation will be fair and thorough, and it will be conducted as expeditiously as possible." It's not clear how long it will take; an investigation is still pending into the death of Michael Brown, the 18-year-old who was shot dead by a police officer in Ferguson, Missouri.

Pantaleo could face federal criminal charges. In 1998, police officer Francis Livoti was convicted of violating Anthony Baez's civil rights in a 1994 chokehold case and sentenced to 7 1/2 years in prison. He had been acquitted of criminal charges by a state judge.

INTERNAL AFFAIRS INVESTIGATION:

The New York Police Department will conduct an internal investigation into the incident to determine whether Pantaleo violated policy. Commissioner William Bratton said interviews would begin Friday. The probe will be conducted simultaneously with the federal investigation.

Pantaleo's attorney and union have maintained that the officer used a takedown move taught by the police department, not a banned maneuver, because Garner was resisting arrest. They said Garner's poor health was the main reason he died. "You cannot resist arrest, that's a crime. Police officers do not have the option to walk away," said Patrick Lynch, president of the Patrolmen's Benevolent Association.

Pantaleo could face a departmental trial that could result in administrative charges like loss of vacation days or suspension, or dismissal. Regardless of the administrative judge's finding, the police commissioner has the final say on the officer's future with the force. The officers involved in the shooting death of Sean Bell, killed in hail of bullets on his wedding day, were fired after an internal affairs investigation. They had been acquitted at a bench trial of criminal charges.

CIVIL LAWSUIT:

Garner's family filed a notice of claim in October, the first step in filing a civil suit against the city. Attorneys said the family will seek $75 million in damages alleging wrongful death, assault, emotional distress and negligent training.

Civil cases generally require a lower standard of proof than criminal cases. Jurors must find a preponderance of evidence, not proof beyond a reasonable doubt needed to convict in a criminal trial.

The family of Amadou Diallo, an unarmed man was killed by police in 1999, settled with the city for $3 million in 2004 after filing a $60 million lawsuit. The city did not admit any wrongdoing. Garner family attorney Jonathan Moore said Thursday they had been waiting on the outcome of the state case before filing their lawsuit, and may wait on the federal case.
