A suspected serial killer already serving a 100-year federal prison sentence for crimes committed during a spree of burglaries is set to go to trial Tuesday for the killing of a mother and daughter in Prince George's County in 2009 -- one of two sets of mother-daughter killings investigators think he committed.

A suspected serial killer who was set to face first-degree murder charges this week in the slaying of a Largo woman and her daughter will undergo a mental competency exam to determine whether he is fit to stand trial, according to Prince George's County court records.

A man who remains a suspect in three killings in Prince George's County was sentenced Tuesday to 100 years in prison for unrelated crimes committed during a string of robberies.
