ROTHBURY, Mich. — Michigan State Police (MSP) detectives shared some more information Friday about their investigation of the infant death at this year’s Electric Forest music festival in Rothbury.

Troopers recently received a tip about a Muskegon woman who was said to have information about the incident, but after interviewing her and completing other necessary investigative steps, MSP said they ruled her out as a suspect.

A restroom vending company employee at the festival found the body of a neonate, a newborn infant who is four weeks old or younger, in a portable restroom in the festival camping area on June 28, according to troopers.

The festival is hosted at the Double JJ Resort, which was locked down to anyone entering the following day as police surrounded the scene.

Troopers are asking for tips from the public at michigan.gov/michtip.

GRAND RAPIDS, Mich. (WOOD) — Harmful algal blooms have been reported on two notable lakes in West Michigan: Gun Lake and Muskegon Lake.

The Michigan Department of Environment, Great Lakes and Energy says cyanobacteria was reported on Muskegon Lake July 3, but no tests have confirmed it.

The Barry-Eaton District Health Department says a harmful algal bloom was confirmed Thursday on Gun Lake. The lake remains open, but the BEDHD is encouraging visitors to use caution and avoid water that has “visible algae.”

Visitors are encouraged to avoid any contact with water that appears bright green, blue-green, brown or red or has “floating mats of scum.”

Pets should also avoid the water. If they come into contact with the algae, pets should be rinsed off as soon as possible with clean, fresh water.

Exposure to algae can cause a rash or irritation to the skin, eyes, nose and throat. It can also cause stomach cramps, nausea, vomiting, diarrhea, headache, fever and trouble breathing.

“If you become sick, contact your healthcare provider. Seek medical care right away if you have trouble breathing, severe vomiting, or other serious symptoms,” the BEDHD said in a statement. “If your pet was exposed, rinse them well with clean water and do not let them lick their fur until they have been washed. Contact your veterinarian right away if your pet has vomiting, diarrhea, weakness, trouble walking, excessive drooling, shaking, or seizures.”

Harmful algal blooms are powered by the sudden growth of cyanobacteria, also known as blue-green algae. Cyanobacteria occur naturally in lakes, rivers and ponds but is often boosted by a sudden excess of nutrients, often caused by fertilizer runoff from farms or failed septic systems.

They can last for several days and sometimes even months. The water will look “scummy” or like “spilled paint or pea soup.” They are typically found in the summer and fall — usually peaking in August or September and dying off by the end of October.
