A 20-year-old Nigerian boy by name Isaac Anya Ojiabo Jr. has been charged with first- and second-degree murder and assault with a deadly weapon after his mother was found dead in their palatial home in Forest Hill, Baltimore, USA.

A Baltimore Sun report said he was taken into custody after allegedly stabbing his mother to death on Wednesday and is being held without bail at the Harford County Detention Center in Bel Air.

The report quoted the Harford County Sheriff’s Office as saying that he was apprehended early yesterday morning without incident, after detectives found him in his 2007 Lexus SUV at Crouse and Putnam roads near his neighborhood at about 5 a.m.

Sheriff spokesman Edward Hopkins was quoted as disclosing that Isaac’s mother, 51-year-old Joy Ojiabo, was found dead in the 1600 block of Rushing Stream Court. He said she had been stabbed in the chest and that her husband, Anya Ojiabo, found her in a room on the second floor, after which her body was taken to the Office of the Chief Examiner in Baltimore for an autopsy.

“A motive has not been identified, but Hopkins said there is a history of domestic problems at the house. Police were sent to the residence in March for a ‘verbal family argument,’ and in September and December for two alleged fights between mother and son,” Baltimore Sun reported.

Citing state tax records, the paper said Isaac Ojiabo Sr. and Joy Ojiabo acquired their 6,100-square-foot home from builder Toll Brothers in November 2007, paying $1,032,847 for the house and one-acre lot.
