Baby Rescued In Colorado Hostage Crisis [UPDATED]

Police in Colorado are preparing to end a standoff with a man who is holding his six-month-old daughter hostage inside his ex-girlfriend's residence in La Salle, Colo.

"We are waiting to get a search warrant and arrest warrant signed, which should be taking place soon," Weld County Under-Sheriff Margie Martinez told The Huffington Post. "Once that is signed the SWAT team will make entry."

Officers surrounded the home in the 200 block of Ley Drive at about 1:30 a.m. and have worked to establish contact with the man inside the home, whom police have identified as 44-year-old Gabriel Esparza. So far those attempts have been unsuccessful.

"We don't know if there's any weapons or not and cannot hear anything inside the residence," Martinez said.

According to police, the hostage situation was allegedly triggered by an argument between Esparza and the child's mother, 19-year-old Tammy Dansko. The two were involved in a heated argument, during which Esparza allegedly assaulted and threatened kill Dansko, police said.

Martinez said there is a restraining order between Esparza and Dansko, but the details of that order are not yet known.
