FORT ATKINSON, Wis. - Fort Atkinson police say they are looking for a father that took three children against the wishes of his wife and has not been seen since Monday.
A statewide crime alert sent Saturday evening says Hui Zhu was last seen on Monday at 2 a.m.
On Sunday, police said they received information that Zhu may be armed with a firearm.
According to the release, Zhu phoned his wife Meixin Lin Monday at 10 a.m. and stated he was at O'Hare airport in Chicago and was going to take his three children to China.
The release said Lin asked Zhu if he wanted her to pick the children up so he could go to China alone and he disconnected the call.
Police tell WISC-TV that they confirmed the father and children never boarded a flight.
Police say Zhu left in a 2015 white Ford F-150 with Wisconsin plate LH4873 with $7,000 and the children's birth certificates, and that the vehicle was last seen in the state of West Virginia on Wednesday.
Authorities are now looking for Zhu and his 3 children, 3-month-old Elina Zhu, 3-year-old Evelyn Zhu and 11-year-old Jefferson Zhu.
Police urge the public to use caution when encountering him. The public is asked to call 911, and not approach if he is seen.
