Police Question Person Of Interest In Disappearance Of 1-Year-Old Jaclyn 'Angel' Dobbs, Murder Of Her Mother

CHICAGO (CBS) -- Police late Thursday questioning a person of interest in Missouri, in connection to the murder of 21-year-old Ja'Nya Murphy in Wheeling, and the disappearance of her 1-year-old daughter, Jaclyn "Angel" Dobbs.

Meanwhile, a body was found in a retention pond in off I-80/94 in Hammond, Indiana on Thursday afternoon, and Wheeling police sources believe it belongs Jaclyn. CBS 2's Jackie Kostek confirmed the discovery of the body Thursday afternoon. Indiana State Police are set to provide an update at 4:15 p.m.

Jaclyn's mother was found dead in their Wheeling home Tuesday night. Jaclyn had been missing ever since.

Police said they believe Murphy was strangled, and that Jaclyn was taken away in a maroon 2020 Dodge Grand Caravan with Illinois license plate FP139293. The vehicle was later located in western Missouri, but Jaclyn was not with the vehicle and is believed to be in danger.

Police also said investigators identified a person of interest based on video evidence. Police said the person of interest has also been located in Missouri and is being questioned.

Police said the person of interest had a "previous relationship with Ms. Murphy" but is not Jaclyn's father. Three were last seen together on Monday at a suburban shopping mall.

Murphy was found dead around 10:20 p.m. Tuesday, when officers conducted a well-being check at her home in Wheeling, after receiving a missing person report, because she hadn't shown up to work or contacted her family since Monday.

When officers arrived at the home, they found the door unlocked, and Murphy dead inside. Jaclyn was missing and has yet to be found.

Anyone with information on Jaclyn's whereabouts is asked to call police at 847-459-2690.
