The father of a 6-month-old California baby is considered to be a person of interest in her disappearance, becoming the subject of a manhunt after he stole a gun and fled, authorities said Saturday.

Shasta County Sheriff Tom Bosenko said Matthew Graham, 23, skipped a meeting with his probation officer and stole a semi-automatic pistol from his mother after learning new information about the investigation.

Bosenko said deputies had spoken to Graham’s mother and the baby’s mother about a pacifier found in a sparsely populated Ono on Friday.

The Record Searchlight reports that Graham called after the meeting with police about a missing gun, cellphone and cash.

“Matthew has violated his probation. He is a felon in possession of a gun and should be considered armed and dangerous,” Bosenko said.

Graham reported his daughter’s disappearance from his Happy Valley home in the early-morning hours of July 2 telling authorities she was last seen in her crib. He became a person of interest after giving inconsistent information to investigators.

Graham was jailed on an unrelated probation violation stemming from driving under the influence and a forgery conviction, but was released this week after pleading guilty.

A judge ruled that he didn’t have to wear a monitoring bracelet after settling the case.

"The court made a bad decision in ordering Graham's GPS to be removed and now the public is in danger," Bosenko said.  

Meanwhile, a search was continuing in the Ono area for the infant after the discovery of the pacifier. Bosenko said the pacifier resembled Ember's and will be put through DNA testing.
