Authorities in Texas are looking for a 10-year-old boy believed to have been taken by his father after the man allegedly killed the child's mother. 

An Amber Alert was issued Tuesday night for Ian Aguilar from Wilmer. Investigators say he is with 38-year-old Juan Aguilar-Cano, who the Dallas County Sheriff's Department told FOX 4 is the suspect in a homicide investigation. 

Police announced Wednesday that the tan 2007 Chevrolet Tahoe with Texas plate KVZ1194 the two were believed to be traveling with has been located, but the child and suspect have not.

While the boy's mother has not been identified by authorities, neighbors told FOX 4 that a relative found her dead inside the mobile home on Oakdale Street that she shared with the father and son.

Wilmer police believe Aguilar is in "grave danger." 

"It was initially reported as a welfare concern and after some investigation we found that a homicide had been committed. Immediately, our concern was for the 10-year-old boy and his safety," Wilmer Police Chief Victor Kemp told the TV station.

The Dallas County Sheriff's Department is reportedly handling the murder investigation because Wilmer Police Department does not have any homicide detectives.

Child Protective Services and police told FOX 4 they have never been called out to the family's home prior to the alleged murder and kidnapping. Criminal records for Aguilar-Cano obtained by FOX 4 do not show a history of violence.
