UPDATE 10:43 a.m.
The mother and children returned to the home in the missing truck. Randall Foster is still at large.
Memphis police told FOX13 the mother and children left after the original incident early Thursday morning.
According to Karen Rudolf of the Memphis police, there is some conflicting information about whether or not the mother and children were taken against their will.
The focus of the investigation has now switched to finding Randall Foster. Police fear he may be a danger to himself.
A City Watch Alert has been issued for Randall Foster.
A family is missing, and the Memphis Police Department is working to bring them home.
Shortly before 12:30 a.m. on Thursday, police responded to the 400 block of North Graham in High Point Terrace. They went inside and saw signs of a disturbance, but the house was empty.
Police said blood was found in the home. Crime scene tape is blocking off the scene as police continue to search for evidence.
Memphis police issued a City Watch Alert and said the father, Randall Foster, is believed to have kidnapped the family.
The victims are Catherine Rippe, 37, Riley Rippe, 15, and Randall Foster Jr., 9.
Officers on the scene told FOX13 they have "reason to believe the family is in danger."
Police think the family may be heading to northern Mississippi since they have relatives there.
MPD said they were possibly traveling in a 2010 Nissan Maxima, however, that vehicle has been located. Police are now looking for a Black 2009 Chevy Silverado with Tennessee plate J3418W.
FOX13 learned this is not the first time police have been called out to the home.
According to an affidavit from Jan. 18, Randall Foster came home drunk around 4 a.m., woke his wife up, and started punching her. He also grabbed her by hair and pushed her around.
The victim declined transportation.
Foster was due in court next Tuesday for the assault.
