A man is in custody after Dallas police say he admitted to cutting his wife's throat and stabbing her to death in their kitchen after she dropped her children at school Monday morning.
According to an arrest warrant affidavit obtained by NBC 5 on Tuesday, 28-year-old Yoni Vasquez-Velasquez called 911 Monday morning and told operators he'd killed his wife.
Vasquez-Velasquez then began walking toward a nearby Dallas police substation where he was stopped by patrol officers. Police said he had blood on his arms and clothing and a bloody folding knife in his pocket.
Meanwhile, officers were sent to the couple's residence on the 4500 block of Lizzy Drive where they found the man's wife, identified as 23-year-old Irma Bonilla, dead from apparent "homicidal violence."
Police said the man was read his rights and that he agreed to speak with detectives.
