Records show there have been at least 17 calls for service to Davis' residence since 2011, most of them this year.
Neighbors described both Davis' residence and the home Benavidez shared with her adult son as “high-traffic.”
Many suspected drug activity played a role in the shootings.
Interviewed the day Nardine was shot, neighbor Lonnie Crego said he was hopeful the random violence would cease in the old neighborhood.
He said the area was fine, “except for the negative influences.”
Crego's wife said she had nightmares the night of the Oct. 9 shooting “because of all this craziness.”
“I don't like it,” she said. “I had a dream my son got shot.”
Women had records
Nardine and Davis each had been arrested before the Oct. 9 shooting, records show, but the victim has the lengthier criminal history.
Davis pleaded guilty to being drunk in public — a misdemeanor — just five days before prosecutors allege she shot Nardine in the neck.
Davis was placed on a three-month probation and was ordered to perform 10 hours of community service.
Nardine has been arrested several times in recent years.
In May 2010, she was arrested after police saw her chasing her husband around their front yard with a knife.
Two years later, Nardine was arrested after it was discovered she had forged 32 checks belonging to a man she was living with. The man's accounts were short nearly $3,000, records show.
In September, police serving a warrant on Nardine found a small bag of methamphetamine in her purse and a stolen check in her front pocket.
Nardine also faced misdemeanor bogus checks charges in September 2011 after she failed to pay off a check for $25.25.
