Matthew Anthony DeMizio, a theater graduate student from Hunt Valley, died of pulmonary failure at University of Pennsylvania Hospital in Philadelphia on Dec. 4. Mr. DeMizio, who was 22, was injured in an automobile accident in Lower Merion Township, a Philadelphia suburb, on Nov. 11.
Born in Livingston, N.J., he moved to Hunt Valley in 1995 and graduated a year later from St. Joseph Parochial School in Cockeysville.
He then enrolled at Calvert Hall College High School, where he graduated in 2000. He worked with the school's television station and appeared on the television show It's Academic as a representative of Calvert Hall. He also was stage manager for two plays, wrote for the school newspaper and worked on its Web page.
"He was a happy kid who loved what he was doing," said Chuck Stembler, Calvert Hall's assistant principal. "I couldn't begin to tell you the number of hours he put in here doing things for us."
He was also an assistant manager for Hoyt's Cinema, now the Regal theaters, in Hunt Valley.
Mr. DeMizio earned a degree with honors from LaSalle University in Philadelphia, where he was a lighting director for school plays. He performed in Godspell and also wrote for the college newspaper.
In August, he enrolled in a Villanova University graduate program in theater and helped stage two productions, Art and The Visit, for which he was the lighting designer.
A Mass of Christian burial was offered Friday at St. Joseph Roman Catholic Church, where he had served as an altar boy.
Survivors include his parents, Carol Ziobro DeMizio and Anthony DeMizio of Hunt Valley; a sister, Christina Noelle DeMizio of Hunt Valley; his grandmothers, Elfriede DeMizio of Monroe, N.J., and Stephania Kubas Ziobro of Elizabeth, N.J.; and four cousins.
