A second suspect has been arrested in connection with the disappearance of 18-month-old Kytana Ancog.

The Honolulu Police Department identified the suspect, a 48-year-old man, and arrested him on suspicion of second-degree murder just before midnight Saturday.

About two weeks ago Kytana was dropped off at the residence of Travis Rodrigues, whom HPD identified as her father.

According to a family representative, the toddler’s mother, Ashley Ancog, was apparently not feeling well, and on Jan. 31 dropped off Kytana at Rodrigues’ residence on Kaulainahee Place in Aiea.

Kytana and Rodrigues, 40, had been missing until Saturday. An ongoing HPD investigation found “foul play was involved” in the miss- ing-­person case, and Rodrigues was subsequently arrested in the Ko Olina area Saturday afternoon on suspicion of second-degree murder.

Rodrigues, who is also known as Travis Heffelinger and Travis Heffelfinger, had served time in federal prison for felony drug and weapon convictions. Rodrigues has a long rap sheet, but the family representative said Ancog would not have left her daughter with Rodrigues if she thought he was going to hurt her.

Previous reporting by the Honolulu Star-Advertiser revealed that Lisa Mora, Kytana’s grandmother, had “never heard of” or met Rodrigues, and is unclear of the relationship between the two.

Mora said her granddaughter’s birth certificate does not list Rodrigues as the father.

Rodrigues had been living with his grandfather Leroy Rodrigues, owner of the Kaulainahee Place residence. Leroy Rodrigues declined to speak with the Star-Advertiser.

Kytana remains missing, as HPD has yet to report her location.

Charges have yet to be filed against Rodrigues and the other suspect, but both are still in custody.
