David Allen Van Dyke (born January 14, 1959) is an American serial killer who bludgeoned, beat, and stabbed six people to death at their residences in Milwaukee, Wisconsin, between 1979 and 1980.

[3] Between July 1979 and April 1980, Van Dyke murdered four women and two men at their residences in the same area of northern Milwaukee.

He then fled the scene, leaving the weapons he used – a tire jack, ice pick, claw hammer, knives, or scissors – behind.

[6] On August 10, 1979, Van Dyke stabbed 78-year-old Florence Burkard in her North Side home 43 times with a pair of scissors, the fatal wound being to her heart.

[3][7] Van Dyke beat 79-year-old Helen Wronski to death in the living room of her East Side home.

A few days before his death, he gave a note to his downstairs neighbors with the name and address of Fonder's former roommate, who had beaten him the previous December.

In turn, the roommate was initially charged with Fonder's murder, but released after fingerprints found at the scene did not match his.

[3] She managed to escape her house, first running to a nearby home, where the occupant shut the door on her, then to a tavern, where she received help.

[2] On April 25, 1980, Van Dyke sexually assaulted and beat 30-year-old Helen Louise Bellamy to death in her North Side home with a tire jack.

Her 13-year-old son discovered her body partially covered with a sheet in the dining room when he returned home from school.

[3] Police sought two men wearing overalls, who may have been impersonating television repairmen, in connection to her murder.

When asked to explain the cuts on the woman's arms, he proposed that she injured herself by falling on a broken bottle.

After deliberating for four-and-a-half hours, the jury found Van Dyke guilty on all charges, and he was given six life sentences.
