Lansing police say they want to question 24-year-old Kelvin "Monroe" Bates about a fatal shooting late Friday night.
Bates is not in custody, but police said they won't rest until he is.
"We want them [the family] to know we will conduct an objective investigation, and we will be tenacious, and we will persevere," said Lansing Police Captain Daryl Green.
36-year-old Micah Arnold died shortly after he was shot repeatedly in the 3100-block of Turner Street late Friday night.
Police describe Bates as a "person of interest," not yet a suspect.
"We have strong partnerships, state, federal, that are assisting us in this matter as well, and it's in his best interest to contact the Lansing police department as soon as possible," Captain Green said.
Police said Bates is probably armed and dangerous. He is a Lansing resident, but it's possible he fled. Right now everyone wants answers from him, especially for the three children Arnold left behind.
"He was really trying to raise his children and be a positive impact in their life," said Arnold's close friend Charity Jones. "There's no telling what these children are going to go through without their father."
Police said this was an isolated incident, and Arnold was targeted. Nevertheless, the neighborhood was deeply impacted, and Lansing Mayor Virg Bernero said he wants to make sure they feel safer.
"We all want much better than this for our children, and we're digging into that community," Mayor Bernero said. "We're going to help them create a neighborhood watch to try to build more community there and across this city."
Some feel that might not be enough to stop these senseless acts of violence, in this case supposedly over a broken bottle.
"He killed my friend for no reason," said Machelle Dorris, a close friend of Arnold's who witnessed the shooting.
Residents fear for the many children that live in the Turner Street neighborhood. They play outside frequently on the sidewalks that go from blood-stained to covered in candle wax from a vigil to remember the most recent homicide victim.
"This is what's breeding. This is generation after generation happening," Jones said.
Police said the investigation is moving quickly, and they hope to make an arrest very soon.
