Reference excerpt

The murder of Dolores Della Penna is an unsolved murder case dating from July 1972 in which a 17-year-old high school graduate was abducted, tortured, murdered and dismembered by an unknown number of individuals in Kensington, Philadelphia. Her dismembered torso, arms and legs were later discovered in New Jersey, although her head has never been found. Although the motive for Della Penna's abduction and murder remains unclear, investigators believe she may have been targeted by drug dealers either due to her being falsely blamed by former roommates for the theft of drugs or in an act of revenge against her boyfriend relating to an unsettled drug debt. The case itself has been described as one of Philadelphia's most gruesome and enduring unsolved murders.

Early life Dolores Marie Della Penna was born in Tacony, Philadelphia on December 13, 1954, the second of two children born to Ralph and Helen (née DiMichele) Della Penna. Her father was a chemist, and her mother a homemaker. The family resided in a semi-detached house in a blue-collar section of Tacony composed predominantly of families of Polish or Italian ancestry. By 1971, Della Penna's older brother, Ralph Jr., had married and moved into his own house. An honors graduate of St. Hubert Catholic High School for Girls, Della Penna was described by her parents as a "kind, obedient and family-oriented" girl who was markedly studious and refrained from conflicts. She held aspirations to attend college in September 1972, with aspirations to ultimately become a radiographer. Della Penna did not own a car, although unbeknownst to her, her parents had plans to purchase a car for her eighteenth birthday.

Graduation Della Penna did not attend her high school prom following her June 1972 graduation, and according to her sister-in-law, Della Penna viewed the summer following her graduation as one which she intended to take full advantage of as it would be "the last summer she could enjoy before she had to work for the rest of her life". Her sister-in-law would also state that by approximately January 1972, Della Penna had become somewhat acquainted with several Kensington teenagers whom she knew to occasionally experiment with drugs, and that by the spring of 1972 Della Penna would travel to socialize with these individuals approximately four times per week. Shortly after her graduation, Della Penna and three female friends with whom she had recently become acquainted opted to rent a bungalow upon Forget-Me-Not Road in Wildwood Crest, New Jersey, with view to renting the property solely for the summer of 1972. The property was located approximately 95 miles (153 km) from her parents' home, and the money necessary to rent the property was provided by Della Penna's parents as a gift for her having graduated with honors from high school. In late-June, Della Penna learned her parents, older brother and other family members planned to visit Walt Disney World. According to her mother, upon hearing this, Della Penna informed her, "You're not going without me." The entire family commenced their 10-day vacation on July 1, returning home on July 10.

July 11, 1972 On the morning of July 11, 1972 Della Penna assisted her mother with several household chores; that afternoon, she composed several songs upon the family organ before visiting a local store to purchase cigarettes. Shortly after returning home, she spoke with several friends on the telephone before making plans to meet two friends named Carol Nichols and Betty Nicastro that evening.

Abduction At approximately 8 p.m. on July 11, Della Penna, Nichols and Nicastro hitchhiked from Tacony to Kensington to visit Nichols's fiance. Shortly after 11 p.m., Della Penna and Nichols left her fiance's home, with both girls intending to take separate trolleybuses to their homes. According to Nichols, her friend exited the Route 5 trolleybus upon which both had been traveling at the corner of Frankford and Torresdale Avenues, where Della Penna expressed mild dismay at having just missed her intended connecting Route 56 trolleybus home and remarking to Nichols she would "have a twenty minute wait" for the next bus. Nichols remained aboard the Route 5 trolleybus. Della Penna is known to have boarded the next Route 56 trolleybus to arrive at this bus stop at approximately 11:39 p.m. The driver of this trolleybus, Joseph Kilcoyne, would later inform investigators the girl alighted his trolleybus at the corner of Knorr Street—three blocks and approximately one mile from her home—sometime between 11:50 and 11:55 p.m. According to an eyewitness to her abduction, Della Penna was attacked by a slender, brown-haired white male aged between twenty and twenty-five after she had walked approximately one block from the trolleybus stop. This witness observed Della Penna being beaten, then swiftly dragged "kicking and screaming" into a maroon 1965 or 1969 model Chevrolet parked close to her own home and hastily driven from the scene. The sole evidence recovered at the site of Della Penna's abduction was her maroon jacket, door key, a small cross and a crucifix which had been gifts given to her by friends at her high school graduation.

Worked examples

Example 1 — a first encounter with Murder of Dolores Della Penna

Start with the simplest possible case. Write down what Murder of Dolores Della Penna claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Murder of Dolores Della Penna before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Murder of Dolores Della Penna ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Murder of Dolores Della Penna

In research
Murder of Dolores Della Penna appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Murder of Dolores Della Penna in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
