At least one knife was introduced in a fight between two brothers in the family home in Irvine Sunday night, resulting in the death of
32-year-old Daniel John Sullivan and murder arrest of Laurence William Sullivan, 33, police say. The cause of the altercation is still under investigation, according to a statement from Irvine Police Lt. Julia Engen, the department spokeswoman.
About 10 p.m. Sunday, police and the Orange County Fire Authority were called about a possible assault in the 4100 block of Old Mill Street in Irvine. Dispatchers were told one brother stabbed the other multiple times.
Officers arrived to find both Sullivans nursing wounds. Daniel Sullivan was taken to a nearby trauma center, where he later succumbed to his injuries and was pronounced deceased at 11:23 p.m. Laurence Sullivan was treated for non-life-threatening injuries at a local hospital.
Just after 7 a.m. this morning, Laurence Sullivan was arrested by Irvine detectives on suspicion of murder and booked into Orange County Jail. Bail has not yet been determined. Police do not believe anyone other than the two brothers were involved in the altercation.
