A confrontation over an affair may have led to a shooting this weekend that left a little girl without both of her parents.  

Steven Santiago and Adrian Ramirez were shot to death early Saturday morning outside their home on S. Hall St. in Allentown while their daughter and a friend slept inside.  Now, a neighbor and a teenager boy are charged with the crime.

As memorial candles flickered at the shooting site on Monday, those who live nearby are trying to understand why one neighbor allegedly turned on another so violently.

"Who knows?" asked Cathy Lambert, whose daughter was inside the victims' house during the shooting.  "Just people are crazy."

At the center of the case is John Jermaine Boyd, 27, who lives just a block away.  According to an arrest affidavit, Boyd was having an affair.  His apparent mistress told police that she and Boyd drove to the victims' home that morning, perhaps to confront them about what they knew.  When they arrived, Boyd's wife was already there.  An argument erupted among everyone.  It's not clear exactly what was said, but witnesses said it ended with Boyd and a 16 year-old friend, Tykweis Wade, pulling out guns and shooting.

According to arrest papers, one witness heard a suspect, peeling out in a getaway car, say, "We really aired out that place."

Ramirez's friends still can't understand why she had to die.

"She didn't bother anybody," said Lambert.  "He didn't really bother anybody."

John Boyd served almost a year in a prison in New Jersey on a weapons possession charge.  Police said they are still trying to piece together why he and a 16-year-old boy were together that night, though neighbors said Wade was a regular around the block.

"That's the even scarier part, because it could have been anybody," said Lambert.

Credit swift police work for solving the case so quickly.  The suspects got only a block and a half away before officers caught up with them.  They recovered both weapons stashed in a basement on Sixth Street.

Both suspects were committed to the Lehigh County Prison without bail.  Their next court appearance is set for December 23.
