He stared straight ahead during the short hearing and did not say a word.

His bail was set at $10 million.

He has been charged charged with two counts of first-degree murder.

If convicted, he would receive an automatic sentence of life in prison without parole. A statement from Des Moines police said the investigation has produced probable cause to support the charges.

It was also revealed Greene was arrested on Wednesday with the handcuffs that had belonged to the patrolmen who were killed in ambush-style attacks, Des Moines Sgt. Anthony Beminio, 39, and Urbandale officer Justin Martin, 24.

Greene surrendered to a state Department of Natural Resources officer in Dallas County about 9am.

Greene, an unemployed father who lived in the Des Moines suburb of Urbandale, was behaving erratically and was increasingly desperate for money in recent weeks, court records show.

District Judge Carla Schemmel ruled Tuesday Greene had committed elder abuse against his 66-year-old mother, Patricia Greene, by 'physically hitting and financially exploiting' her. She ordered him to move out of his mother's home, where he had been living in a basement bedroom, before November 6 and to stay away from the home for a year.

Patricia Greene had applied for the restraining order Oct. 19, two days after she was arrested and charged with striking her son in the face during an altercation that he recorded with his cellphone.

She wrote in the application that she believed her son 'set me up to get me in trouble.'

Patricia Greene wrote that while she was in jail, her told one of her friends she needed to give him $20,000 and that if his mother paid, 'he would move and not bother' her again.

Both shootings happened in the Des Moines suburb of Urbandale, where the local police department has just 50 officers

The 66-year-old also wrote that her son had sent an acquaintance 'a bunch of rambling, offensive' text messages, warned that he would no longer take care of her cat and was going through her personal belongings. She said her son had subjected her to mental, emotional and financial abuse.

A temporary protective order was issued Oct. 20. Schemmel issued the permanent order during Tuesday's hearing, where it was served on Greene.

The order, which warned that any violations would lead to his arrest, also directed Greene to return $10,000 to his mother and to not take any of her assets.

Beminio, 38, and Martin, 24, were shot after 1 a.m. Wednesday while sitting in their patrol cars in separate incidents less than 2 miles apart. Several bullets were fired into the vehicles.

The .223-caliber rifle believed to be used was discovered Wednesday by a police dog apparently hidden in a wooded area 'where no person probably could have found it,' said Des Moines police spokesman Sgt. Paul Parizek.

Parizek thanked the community for its outpouring of support and said the officers represent 'the security blanket you guys sleep under every night.' He said a motive for the shootings remains unclear.

It also emerged on Thursday that Greene had a pro-Donald Trump sign in the yard outside the home he shared with his mother.

Neighbors say the sign was put up in the yard about two weeks prior to the shooting.

A Facebook account belonging to Patricia Greene has a number of pro-military and Blue Lives Matter posts. She does not mentioned Donald Trump by name in her comments.

One post, which was shared last month, reads: 'KILLING A POLICE OFFICER SHOULD BE A MANDATORY DEATH SENTENCE.'

Having the sign in his front yard does not in any way link the shooting to the Republican presidential nominee.

Beminio had been promoted to sergeant last year after about 10 years on the police force
