TAMPA (WFLA) – Gabby Petito’s family attorney has announced the family will be holding a press conference Tuesday at 1 p.m. in New York, according to NewsNation’s Brian Entin.

The Petito family has not spoken since the funeral of their daughter was held on Sunday afternoon.

Hundreds of mourners on Long Island stood in a line that wrapped around the block to attend a public memorial service for Petito on Sunday.

Petito was reported missing by her parents on Sept. 11 after she did not respond to calls and texts for several days while she and her fiancé Brian Laundrie, 23, were on a cross-country camping trip out West.

After the missing persons report was filed, police discovered Laundrie had returned to his parents home in North Port, Florida, alone in the van on Sept. 1. He later became a person of interest after he refused to cooperate with investigators.

On Sept. 17, Laundrie’s parents told investigators they had not seen their son since Sept. 14. Police continued to search for him on Sunday, as Petito’s family prepared to lay her to rest.

Petito’s body was found in a remote area of Grand Teton National Park in Wyoming on Sept. 19. Her death was deemed a homicide, meaning it was caused by another person. How she was killed was not disclosed by the medical examiner, pending further autopsy results.

Law enforcement officials have since issued an arrest warrant for Laundrie. He allegedly used a debit card and PIN to buy more than $1,000 worth of items between Aug. 30 and Sept. 1, according to the indictment.

His family’s attorney noted the warrant is not for Petito’s death.
