Scroll down for video . Temitope Adebamiro, 35, was charged with murder on Friday after her husband's death was ruled a homicde . Police were called to a home in Bear, Delaware, early on Thursday and found Adeyinka Adebamiro stabbed . Paramedics pronounced him dead about an hour later and the Delaware Division of Forensic Science ruled Adeyinka’s death a homicide, according to the News Journal. The husband, Adebamiro, their two children and a nanny had been living at the home for two years. Adebamiro, 35, and the victim had been married for more than ten years, although she told police he had physically abused her while she was pregnant, cheated on her with several women and sent her to Nigeria on multiple occasions. She said he last sent her to Nigeria over Christmas so he could spend it with the nanny's daughter. Detectives determined there was a verbal argument that led to a physical altercation. The argument allegedly began after the victim found photos on Adebamiro's cellphone that she had taken of pictures he had stored on his mobile phone. The stored pictures were of Adebamiro's sister and the nanny's daughter. At some point after the argument, a single stab wound severed the victim's carotid artery and jugular vein. Adebamiro's story about what happened changed several times and she suggested that her husband killed himself as well as mentioned a power outage that never happened. She did not ever admit to the killing, but investigators felt there was enough evidence to charge her. In addition to murder, Adebamiro was charged with possession of a weapon during the commission of a felony. She was arraigned and committed to the Delores J Baylor Women’s Correctional Institution where she is being held without bail.
