DETROIT, MI -- The fifth person arrested in connection with the savage mob beating of Steven Utash on April 2 has now been charged.

Wayne County Prosecutor Kym Worthy's office is charging 19-year-old Latrez Cummings with assault with intent to murder and assault with intent to do great bodily harm.

Worthy's office charged an unnamed 16-year-old with assault with intent to do great bodily harm and ethnic intimidation Thursday. She said there is not adequate evidence to convict the other four suspected assailants with racially motivated cimes.

"As in all cases with multiple defendants, we must evaluate each person’s actions individually to assess their alleged criminal conduct," Worthy said in a statement. "In the case of the 16-year-old charged as a juvenile, we can prove beyond a reasonable doubt the crimes of assault with intent to do great bodily harm and ethnic intimidation.

"In the case of the four adult defendants that have been charged, the facts and the evidence does not support a charge of ethnic intimidation. We know there were numerous people involved in this case and the police are continuing to investigate, so I will not comment any further about the case.”

Utash, a 54-year-old father of three from Roseville, remains unconscious and in critical conditions.

Police say Utash was attacked by up to 12 people after he accidentally struck 10-year-old David Harris, who walked in front of his pickup. Utash exited his vehicle to assist when the beating ensued.

Harris suffered a broken leg.

Detroit Mayor Mike Duggan met with the family personally and helped plan a candlelight vigil for Utash set to take place at 7 p.m. tonight at Little Rock Baptist Church, 9000 Woodward in Detroit.

Family members hoped to raise $50,000 for Utash's medical bills. In six days more than $150,000 in contributions have been made to the online funding site.

Deborah Hughes, a retired nurse who lives near the scene of the attack, is credited for intervening and possibly saving Utash's life. Detroit Police Chief James Craig visited her apartment Tuesday to personally thank her.

Detroit police initially said there was no evidence to support racial motivation in the attack, but earlier this week said they were "widening" their investigation and not ruling out hate crimes.

Utash is white. Harris and his attackers are black.
