LOWELL (CBS) -- A man has been arrested in connection with the death of 22-year-old Dejah Jenkins-Minus. Leonard Robinson, also 22, of Lowell, was charged with murder, according to the Middlesex District Attorney's Office.

According to the D.A., Robinson killed Jenkins-Minus in a Lowell home on Thursday. Police were called to the scene around 10:45 a.m. to do a wellbeing check on Jenkins-Minus and her two-month-old daughter.

She was pronounced dead at the scene and a medical examiner later ruled her death a homicide by multiple sharp force injuries.

Her baby is safe.

Police obtained a search warrant for the Llewelyn Street home and recovered multiple items, including a knife that appeared to be the murder weapon.

Robinson will be arraigned on Tuesday morning.
