Families of Homicide Victims Still Hoping for Justice

DES MOINES, Iowa -- Des Moines Police say on average it takes detectives seven days to make an arrest in a murder case.

However, three out of this year's nine homicides remain unsolved.

"Somebody is sitting back eating their food and watching TV and thinking they got away with something," said Lisa Barber. "But you can`t get away with nothing."

Barber's longtime boyfriend, Scott Perez, was walking to a gas station when he was shot in the 4000 block of Crocker Avenue back in May.

Perez was the father of Scalicity Perez, who he was killed last November in a car accident.

The driver of the vehicle was Troy Mure. Mure was rumored to be involved in a 2015 nightclub homicide.

He's also rumored to have played a role in this murder case.

"We`ve had questions ranging from is it drugs, is it gangs, is it retaliation for Mr. Mure`s connection, we haven’t established any of those connections right now, and that`s the piece we are missing, the other party involved,” said Des Moines Police Sgt. Paul Parizek.

The missing puzzle piece rings true to the shooting death of Victor Robinson Jr. He was shot in the parking lot of the Birchwood Apartments along MLK Parkway in June.

Detectives have interviewed 50 people. They say more than half of them witnessed the shooting but no one is cooperating

The most recent unsolved solved case is that of Dennis Strable.

“I couldn`t believe it. I still can't believe it,” said Brandi Graspy, Strable's niece.

Strable was riding his bike at the intersection of 45th and Kingman Boulevard in July when he too was shot. Detectives have surveillance video of a car in the area they believe is connected to the murder but are still following up on leads.

They are leads his family hopes ends in an arrest.

“It’s just hard to not know anything about it,” said Graspy. “We’re still hurting, we`ve been hurting. It’s hard to get over it without some closure.”
